Things about the metric system that confuse me

Why are there 16 parts to an inch. Like yeah it's divisible by 4 but decimals and percentages on a system based on 100 are so much easier to calculate than fractions.

What are those little sixteenths called

Why don't you have millimeters. What happens if you need to measure something smaller than 1/16th of an inch. Why is your smallest area measurement the length of my fucking thumb

BECAUSE of your dumb inches and sixteenth and fractions, nothing else makes any fucking sense to remember. What's an inch? 16 little notches. What's a foot? 12 inches. What's a mile? 5,280. How the FUCK does anyone remember that. You know what's easy to remember? 10 millimeters are 1 centimeter. Do you know what centimeter means? 1/100th of a meter. You know how many of them are in a meter? 100. Easy shit

Okay this one is at Imperial but whose tablespoon is a tablespoon based off. Why are tablespoons and teaspoons both distinct measurements, they're fucking spoons. They're almost the fucking same. Like if you had "inches" and "binches" and binches were for no reason at all 1/42nd smaller and you only used them for measuring sawdust. Fuck completely off

Okay actually still looking at Imperial and speaking of Teaspoons and Tablespoons, the names don't indicate anything. How would ANYONE simply deduce by name which is bigger or smaller. Why would a spoon for food be bigger than a spoon for a drink. They both gotta fit in your fucking mouth don't they

Did we all standardize our fucking spoon volumes before we standardized our math? And CUPS? Who in the cholera factory was using scientific standard measurements to quality control your cutlery for any of this to be at all reliable for anyone following recipes

Alright back to you Metric WHAT DOES OUNCE MEAN AND WHY IS IT ABBREVIATED AS OZ

WHY IS POUND ABBREVIATED AS LB FOR LIBRA LIKE SCALES LIKE A CRYPTIC ASS ILLUMINATI SECRET MESSAGE WHEN "P" IS PERFECTLY AVAILABLE. YALL AINT PAYING MONEY IN POUNDS AND PENCE SO WHATS THE CONFUSION

Okay also why the hell would the British using Pounds to mean money run away to make America and start using Pounds to mean weight instead. Do I weigh a hundred dollars? Does Chadley at the gym bench press a thousand cents? I hate you

What is a gallon for. What does it mean. You know what's easy to convert to milliliters? Liters. What the hell is an ounce to a gallon

On top of that, what's your measurement transference? We have grams for weight, liters for liquid, meters for distance, and they're all like 1:100:1000 and shit. What do you DO to like. Show how many square inches of mass a gallon has or whatever

Oh shit I ain't even got into Fahrenheit yet

Actually fuck all of us, the end

Hi, friendly neighborhood math teacher here to explain how one would solve the math problem from the Last Stand. (This is for those who, like Emily, may have seen it and just shut down. It’s actually quite simple.)

It helps to draw out a diagram. Here we have a simplified diagram with all of the information we’re given.

But we can’t start to find when these trains collide yet. The Elmville train leaves 25 minutes before the Bastion City train. Let’s fast forward 25 minutes to see how far the Elmville train has travelled at the time that the Bastion City train leaves the station. Since it’s moving at 60mph, that’s an easy conversion to 1 mile/minute. In 25 minutes, it travels 25 miles.

That leaves 110 miles of track between these two trains. One is traveling at 60mph and the other at 70mph, so they are closing that distance at a combined 130mph. Now that we have those two numbers, we need to decide whether our answer will be if they close this distance in 110/130 hours or 130/110 hours.

Did you know that you can manipulate labels just the same as you would variables? Check it out, here’s how we know the right fraction to use.

We can see the label of miles on the numerator and denominator of this fraction, which means they can ‘cancel out’. Now we’re left with inverse hours on the denominator, which is the same as normal hours on the numerator.

You might also, in a less mathematical way, see that they trains will close 110 miles at 130mph, since that’s not 130 miles it will not take a full hour, and 110/130 is less than one while 130/110 is more than one.

Now some calculations to find how long 110/130ths of an hour actually is. For simplification of calculation, I used 11/13ths instead. It’s the same value.

So 11/13ths of an hour as a decimal is .84615 hours. Multiply that by 60 to convert to minutes and you have 50.769 minutes. But we want the exact value, so multiply .769 of a minute by 60 to convert that into seconds, and you get 46 seconds. So the trains collide 50 minutes and 46 seconds after the Bastion City train leaves the station. Add the time we found to 5:30 to find that they collide at exactly 6:20:46.

My brethren in Typhojem, Maul is 5'9, not 5'7.

I see a lot of people claim Maul is 5'7. I see where people are going wrong here, and I'm not setting out to insult anyone, but there is a step missing in your calculation if you got that answer!

See, according to an official (archived) online character encyclopedia, Maul is 1.75 meters tall. Converting meters to feet, you'll see that 1.75 meters is equivalent to 5.74147 feet. It can be tempting to skim this and interpret it as 5 feet and about 7 inches, but that's not quite right!

See, the first digit after a decimal point represents a fraction of that number out of ten. So, for instance, 0.5 is the same thing as 5 over 10, or 5 divided by 10. You can also express them as percentages by multiplying the decimal value by 100, so 0.5 is also the same thing as 50%, or half.

Inches, however, are out of TWELVE, not ten. An inch is one-twelfth of a foot. One foot equals twelve inches. Why do we do this? I don't know. I'm sure it's a very interesting historical story, but for the moment it's basically arbitrary. The point is, 0.7 feet is seven tenths of a foot, and we are looking to measure in twelfths of a foot, which is what inches are.

So we need to convert units a second time: feet to inches. You'll see that 0.74147 of a foot is equivalent to 8.89764 inches. We typically round up for a decimal value that high, so we're looking at approximately 9 inches. Then we go back to the information we got from our first unit conversion, which is that we're adding those 9 inches (which are the same thing as our 0.74147 of a foot from earlier) to a value of 5 feet. Maul is 5 feet and 9 inches tall.

You can also get this information by searching up the real-life height of Ray Park, who portrayed Maul in live-action. Park is listed as being 5'9 on IMDb, with 1.75 meters listed as the metric equivalent of that height.

Maul is still definitely the shortest person in his family, but after all he's suffered, surely we can allow him the dignity of those two inches?

Trying to calculate capital gains on crypto, mostly out of curiosity. (I recently sold some, but not enough to need to report.)

I would have hoped it would be mostly easy. I've been tracking my assets with ledger. So for approximately every fraction of a bitcoin I own, I can see

This is the day I bought it

This is how much I paid

And this is the fees I paid

E.g. "bought 0.00724641 BTC on 2018-05-07, I paid £51.99 of which £1.99 is fees".

There are some exceptions: I have some that I got from mining or from the bitcoin faucet way back when, stored in a wallet on my computer that I couldn't figure out how to access again; I got someone else to do it for me in exchange for about half of what was in there. In my ledger this is just recorded as a 0.03 BTC input that I got given for free. And there's an in-progress bet that involved someone sending me $100 of BTC.

(Other coins are more complicated: I once bought BCH, converted it to BNB, converted that to SOL, moved the SOL to a different place, staked the SOL, moved it back, staked it again and eventually sold, and there's fees involved in lots of these steps.)

But ignoring this I'd hope it would be simple enough? But not really.

I think partly this is because calculating capital gains isn't an objective one-right-answer calculation. If I buy 1 BTC, then buy 3 BTC, then sell 2 BTC, then sell 2 BTC, it matters which order I sell them in.

Okay, but I think FIFO is pretty standard? But I don't think there's a way to specify that I'm doing that or any other approach that could be automated. I just need to manually say "okay, the BTC that I sold here are the same BTC that I bought here", and the way to do that is to specify the date and unit price when I bought them.

Which, I get having this written out explicitly in the file, that seems reasonable, but I'd hope for some way to auto-generate the posting, and I don't see one.

...also I've been letting the unit price be implicit, instead specifying the lot price. Which means the unit price has 16 decimal digits, which aren't written in the file, and which I need to copy exactly when I'm selling or the lots won't quite match up. (Which is mostly fine, but when I want to print lots explicitly it means it doesn't show as "I bought BTC valued at X and then sold them" but as "I bought BTC valued at X and on the same day went into debt for the same quantity of unrelated BTC valued at X±ε".) And sometimes exact isn't enough due to rounding errors.

So I'm converting lot prices to unit prices, which there ought to be a way to do that automatically too but afaict there isn't. (Unless I want to do some python scripting, which might be fun I guess but also might be super frustrating depending how good the API is.)

I've looked idly at hledger as well but from what I can tell it's no better at this. I don't think I've looked closely enough at beancount to know, that might be worth looking into. But I have over 7 years of financial data in ledger and it would probably be annoying to convert it all - just crypto would be fine I guess, but then I'm using two different CLI accounting tools.

A totally different kind of calculator

My latest purchase for The Collection, a Calculated Industries ConversionCalc Plus, was mainly to further diversify my collection, as I now want to get calculators from as many distinct manufacturers as possible. As the name suggests, it's a calculator that is entirely dedicated to the task of converting between different measurements.

I picked the conversion calculator because it is by far the least specialised of all of CI's calculators and just about the only one I could imagine being actually useful to me.

After getting it, it's one of my favourite calculators ever and it goes on my desk rather than on the drawers with most of the calculator collection. I use it whenever I have unit conversions to do because it's so much more convenient than opening a new tab and typing conversions into Google, especially because Google converts to feet with a decimal point by default, instead of feet and inches:

Look Google! It's how people expect feet measurements to be formatted!

Most unit conversions are two button presses away because there's no need to type out their names or dig through menus, everything's at the base or shifted layers of the keypad. I would never use my other calculators for this purpose because they don't prioritise it enough to be faster than Google. It's faster to type "1435 mm to ft" into Google than find the conversions menu in my fx-9750Gii and use submenus every time to slowly type out "[mm] -> [ft]":

After all that effort, it still won't present it in feet and inches!

It of course works as a normal calculator, but has some odd limitations, such as lacking cubes and cube roots. Squares and square roots are elegantly integrated into the unit conversion system. Squaring a metre value will turn it into square metres, and taking the square root of an area will show you the side length of a square with that area, automatically changing from square measurements to linear ones. But none of this can happen with the cubic measurements. Oh well.

Unfortunately, this calculator doesn't support the UK imperial system. All imperial units are the US versions. This is not a huge problem for me as the vast majority of the time I use this calculator will be for communication with Americans.

Converting between units never loses precision. If you convert a number into a new unit, all of the digits of the original unit are retained no matter how many conversions you do afterward. This even applies to entering fractional amounts of inches, which has a special "/" (that is, not the usual divide symbol) button on the calculator. Fractions automatically get converted into a fraction with a power of 2 denominator, but when shown as a decimal value, are clearly still their original value rather than rounded. This is really impressive.

Another great part of the calculator's interface is the unusual number of edge cases built in to display as many digits as possible at all times. If needed, the calculator repurposes its scientific notation/fraction digits into a bonus pair of digits after the decimal place:

I thought this was a bug when I first saw it!

It also has a fourteen-segment display to the left of the main seven-segment display, the first calculator in my collection to feature one. This is used for some of the measurements that don't have dedicated segments in the LCD. But it can also display the minus sign, so MILE ends up dropping the E in sufficiently long negative numbers:

Notice here that it's also using the uppermost segment of the last digit as a minus sign for the scientific notation digits. This seems to suggest that these are not intended to show scientific notation and were originally designed to display inches with fractions, and were then repurposed for scientific notation:

In general, the interface shows an incredibly creative approach to using the LCD panel that I've never seen on any other calculator. Looking through CI's range, some of their other calculators seem to feature a similar or possibly identical display, which suggests it's a standard one that they reuse for all of their calculators.

My collection is now at 19 calculators and I have every major type of calculator:

Standard

Financial

Programmer

Scientific

Graphing

I would consider this another category from all of those, the "unit converter" calculator type. Just as scientific calculators often include programmer functionality in their BASE-N modes, this is definitely not something that this calculator is uniquely capable of, but it is something it's uniquely capable in. It is to unit conversion what my DM16L is to BASE-N arithmetic and logic.

Having a totally new kind of calculator is rare and exciting with a collection my size, which is why I've found the CI converter calculator so much more interesting than my other recent additions, which have been scientific and graphing calculators.

It ticks boxes for my calculator collecting, is genuinely useful to me and has a very unusual set of capabilities and user interface. Love it when that happens!

Statistical Data Types: All You Need to Know

Statistical data is an essential part of any research or analysis. It provides valuable insights and helps us make informed decisions. In this article, we will explore the different types of statistical data and their significance. Understanding these data types is crucial for conducting accurate analysis and drawing meaningful conclusions. I. Introduction Statistical data types refer to the different forms of data that can be collected and analyzed in statistical studies. These data types help us categorize and understand the nature of the information we are dealing with. II. Categorical Data Categorical data includes variables that fall into distinct categories or groups. These variables are usually non-numeric and represent qualitative characteristics. Examples of categorical data include gender, occupation, and marital status. Categorical data can further be classified into nominal and ordinal data. Nominal Data Nominal data represents qualitative variables with no inherent order or ranking. For example, the colors of cars or the types of fruits belong to nominal data. Nominal data can only be categorized and has no numerical significance. Ordinal Data Ordinal data, on the other hand, represents qualitative variables with a natural order or ranking. Examples include movie ratings or levels of education. Unlike nominal data, ordinal data can be ranked or ordered. III. Numerical Data Numerical data, also known as quantitative data, consists of variables with numerical values. These variables can be further divided into discrete and continuous data. Discrete Data Discrete data represents variables that can only take on specific, exact values. These values are usually countable and have gaps between them. Examples of discrete data include the number of people in a household or the number of cars in a parking lot. Continuous Data Continuous data represents variables that can take on any numerical value within a specific range. These values are typically measured and can include decimals or fractions. Examples of continuous data include temperature, height, and weight. IV. Summary Statistics Summary statistics are used to summarize and analyze data. They provide a snapshot of the data set and help in understanding its characteristics. The most common summary statistics include measures of central tendency (mean, median, and mode) and measures of dispersion (range and standard deviation). The choice of summary statistics depends on the type of data being analyzed. For categorical data, the mode (most frequent value) is commonly used. For numerical data, the mean (average), median (middle value), and mode can be calculated. V. Data Visualization Data visualization is an effective way to present and interpret statistical data. Graphical representations help in understanding patterns, trends, and relationships within the data. The choice of visualization depends on the data type. For categorical data, bar graphs are commonly used. They display the frequency or proportion of each category. Bar graphs can easily compare different categories and identify the most common or least common. For numerical data, histograms are commonly used. Histograms display the distribution of values and provide insights into the spread and shape of the data. They can be used to identify outliers or check for skewness. VI. Data Transformation Data transformation involves converting data from one type to another. This can be useful when analyzing data or when certain statistical methods require specific data types. Converting numerical data to categorical data can be done through the process of discretization. Discretization involves dividing the numerical values into range intervals and assigning each value to a corresponding category. Converting categorical data to numerical data can be done through the process of encoding. Encoding assigns numerical values to each category, allowing statistical analysis to be performed. VII. Conclusion Understanding statistical data types is crucial for accurately analyzing and interpreting data. By recognizing the different types of data, researchers can choose appropriate statistical techniques and draw meaningful conclusions. Categorical data and numerical data have distinctive characteristics that require different analysis methods. Summary statistics and data visualization techniques further enhance our understanding of the data. Additionally, data transformation techniques allow for flexibility in working with different data types. By mastering the knowledge of statistical data types, researchers can extract valuable insights and make informed decisions. VIII. FAQs FAQ 1: What are the different types of statistical data? There are four primary types of statistical data: categorical data, numerical data, discrete data, and continuous data. FAQ 2: How are summary statistics used? Summary statistics summarize the characteristics of a data set. They provide measures of central tendency and dispersion, facilitating data interpretation. FAQ 3: What is the purpose of data visualization? Data visualization helps in understanding patterns, trends, and relationships within the data. It provides a visual representation for easier interpretation. FAQ 4: What is data transformation? Data transformation involves converting data from one type to another. It can be useful for analysis purposes or when specific data types are required for statistical methods. FAQ 5: Why is it important to understand statistical data types? Understanding statistical data types is essential for accurate analysis and interpretation. It ensures that appropriate statistical techniques are used and meaningful conclusions are drawn. In conclusion, statistical data types are diverse and significant in any research or analysis. Categorical data and numerical data have distinctive characteristics that require different analysis methods. Summary statistics and data visualization techniques further enhance the understanding of the data. By mastering the knowledge of statistical data types and their analysis techniques, researchers can extract valuable insights and make informed decisions. Read the full article

as much trouble that i had with polar coordinates yesterday i actually am kind of understanding it now so i guess they were right when they said practice makes perfect

i’m so mad about how much time this joke is about to make me waste

[la-principessa-nuova]

I’m seeing a lot of people suggesting doing it by algebra instead, so I thought it would be interesting to point out that the calculations being done aren’t any different, with the minor exception of when people convert from hours to minutes or seconds before rather than at the end. This isn’t to say that method is not valid and might not be faster depending on your particular skills, but it’s an interesting insight into how my brain works and some tricks you can employ to skip steps in problems like this.

The first part where we reduce from 135 to 110 stays the same, but let’s compare the part where we figure out how long from 5:30 until the collision via algebra vs how I described it:

Using algebra, we want to solve for the time t until the collision. We know that each mile either train travels reduces the distance, and the distance traveled by each train over a time period is the speed times t. I’ll keep t in hours, giving us the combined distance d at a given time as:

d = 60t + 70t

But 60t + 70t = 130t, so we have:

d = 130t

They collide after traveling 100 miles, so want to know the value of t when d = 110. This gives the equation

110 = 130t

Now let’s look at what I did originally. I observed that since we can add the two speeds together, we can treat them as one relative speed of 130 mph, and we need to know how long it takes to travel 110 miles at that speed.

We could write this algebraically as:

110 = 130t

It’s the same equation, but when I solved it, I just did the algebra in my head because I know that when a problem can be written as y = xt, it’s the same as saying t = y/x, so there’s no need to write out the algebra.

But I still probably wouldn’t have gotten through the division in time. I think the best chance of getting through the division and multiplication at the end in time would be to stay in hours up until 110/130, and then convert that to minutes and simplify the fraction, to get 660/13.

Then that will directly give you the minutes, and with enough digits of the decimals you can then multiply by 60 again to get the seconds. But time is still super tight on that and you have to know that’s the optimal way to calculate it, and do it under pressure, while being a comedian.

I would describe the problem as theoretically possible to solve within the time limit if one of them had been keeping their really fast computation skills a secret. Like, I know people that could have done this in the time limit, but only a few.

Here’s how the Bad Kids should have solved the problem:

From 5:05-5:30 only the first train is traveling at 60 mph. That’s 25 minutes at 60 miles per hour, a.k.a. 1 mile per minute, which means 25 miles traveled.

We can then reduce the distance left to travel by 25 miles, giving us 135-25=110 miles left to travel.

Now both trains are moving toward each other, so the rate at which the distance decreases (or the speed of one train relative to the other if you prefer) is 60+70=130 mph.

Now we need to know how long to travel 110 miles at 130 miles per hour, so we divide 110/130 and get 0.846153… hours.

Multiply that by 60 to get 50.76923076923076 minutes. Subtract off the 50 full minutes and multiply by 60 again to get 46.153846… seconds.

50 minutes added onto the start time of 5:30 gives us 6:20, and if we add on the seconds and round to the nearest second like they seemed to in preparing the question, we get the correct answer of 6:20:46.

WHAT ARE PIP IN FOREX?

ABSTRACT

You may have heard the terms "pips", "points", "pipettes" and "lots". Now I will explain what it is and how to calculate its value. Arithmetic operations are performed here. only a little.Please take the time to study this material as it is very important for any Forex investor to understand. Dont think about buying or selling until you are familiar with pip values and profit and loss calculations........

WHAT IS A PIP ？

　　A “point” is a unit of measure used to describe the difference in value between two currencies. If EUR/USD increases from 1.1050 to 1.1051, a USD 1,0001 increase in value equals 1 pip. The pip is the last decimal point in the price quote. Most pairs are accurate to four decimal places, with rare exceptions, such as Japanese yen pairs (accurate to two decimal places). For example, EUR/USD is 0.0001 and USD/JPY is 0.01.

WHAT IS A PIPETTE ？

　　There are forex brokers that display currency pairs with a precision of “5 and 3” rather than “4 and 2” to decimal places. They often mean a fountain pipe known as a “dot” or “pipette”.

　　If the concept of “pip” does not cause enough confusion for novice Forex traders , consider the following: A “pip”, “pipette” or “decimal point” is equivalent to “tenths of a point”.

　　For example, if the GBP/USD exchange rate increases from 1.30542 to 1.30543, an increase of 0.00001 USD equals ONE PIPETTE.

　　On the trading platform, fractions are expressed as:

　　On buy and sell platforms, a number representing a tenth of a pip usually appears to be the correct of the two larger numbers. Here is a point “map” to help you find a way to learn points.

How to calculate pip value

　　Each currency has its own relative value, so you need to calculate the pip value for that currency pair. The following example uses quotation marks with four decimal places. To make the calculation easier to understand, we display the exchange rate as a percentage (for example, at 1.2500, the EUR/USD exchange rate is expressed as “1 Euro/1.2500 USD”). Example #1: CAD/USD = 1.0200

　　Multiply USD 1 to CAD 1.0200 (or USD 1 / CAD 1.0200) (the change in the value of the opposite currency) by the exchange rate factor. Same as pip value (default currency)

　　[0.0001CAD] Multiply [1 USD / 1.0200CAD]

　　or [(0.0001 CAD) / (1.0200 CAD)] × 1 USD = 0.00009804 USD per exchange unit.

　　If 10,000 units were sold in USD/CAD, a single tube fume hood with internal replacement filling could be a fume hood for $0.99 (10,000 units x $0.00009804 per unit). The value of each pip is called “roughly” because it fluctuates with the trading rate.

　　Example # 2: GBP / JPY = 123.00

　　Here's another example. This time there is a currency pair in which the Japanese Yen is used as the counter currency. It is worth noting that these currency pairs only provide two decimal places to represent a one-pip difference in value (most other currencies have four decimal places). There will be 1 point move in this situation. 01 yen

　　(the change in the value of the counterparty currency) multiplied by the exchange rate factor gives the value in pip (in the base currency).

　　[0.01 JPY] x [1 GBP / 123.00 JPY]

　　or [(0.01 JPY) / (123.00 JPY)] £ 1 x £ 1 = £ 0.0000813.

　　So, if you trade 10,000 units of GBP/JPY, each pip change is £0.813.

How to find the value of pip in the currency of your trading account.

　　When calculating the pip price for a function, the last query it provides is “How much foreign currency is displayed in my Selling and Buying accounts？”

　　After all, this is a global market and not everyone is on the same Forex now. Therefore, the pip commission must be converted into the currency in which our account is traded. This is probably the most accurate estimate. Multiply or divide the “Setup Fee per Pip” by your foreign currency account and the conversion fee method for that foreign currency. If the “discovered value of pips” foreign exchange is similar to the bottom of the foreign exchange within the replacement fee estimate:

　　Using the GBP/JPY example above, let's convert a published GBP 813 pip price to a USD pip price with the option to use the 1.5590 GBP/USD conversion price ratio. If the foreign currency you want to convert is the relative currency of the conversion rate, you need to divide the “determined pip value” by the appropriate exchange rate factor.

　　£1/$1.5590 = £0.813 per pip

　　or $1.2674 x ($1.5590) per [(£0.813) / (£1)] step.

　　As a result, for every 1.0 pips shift in GBP/JPY, the value of 10,000 positions changes by approximately $1.27. If the currency you want to convert is the base currency of the exchange rate, multiply the “found pip value” by the exchange rate factor. Using the previous USD/CAD example, we want to calculate the pip value of $98 in New Zealand dollars. We use 7900 as the exchange rate factor.

　　Multiply by $0.98 per pip (1 NZD / $0.7900)

　　or [($0.98) / ($0.7900)] 1 NZD × 1 NZD = 1.2405 NZD in one step.

　　In the example above, the value of a 10,000 unit position changes by approximately NZ$1.24 per 0001 USD/CAD pips. Even if you're a math genius right now—at least when it comes to score values—you might close your eyes and think, “Do I really have to calculate all of this？”

　　The answer is an adamant NO. Almost all forex brokers do all this automatically, but it's always helpful to understand how they do it. If your broker doesn't, don't worry. Our pip value calculator can help! Aren't we fantastic？ We'll talk about how this seemingly small amount can be increased in the next lesson.

[deglutitionborborygmus]

i've always considered, (jokingly?) to myself, my calculator to be sentient. every time i'd do something i'd go 'i bet my calculator knows that i'm solving an elastic potential energy problem' or whatever it was i was doing that it would see what i was doing and go 'aha yes this is for a volumes of revolution question' that's a thing i've been thinking to myself consistently for years just as a preface to this.

my calculator has always, i'm sure of it, given numbers as fractions initially then i press the sd button and i get a decimal if that's what i want. i'm sure that that's the way it's always been. i'm sure it was that way this morning. an hour ago. less. but NOW my calculator is giving me decimals. i nearly always convert to decimals, if not to write down, then to see what it is. it's giving decimals first. i'm on the normal mode. i know that this is new because like 15 minutes ago when it first happened my initial conclusion was that i must have pressed sd without noticing. but then it did it again. and now that's what it does every time. and i can't help but think that maybe i was right... maybe my calculator is sentient... maybe it's changed to decimals because i nearly always press sd.

[purple-is-great]

ugh i hate it when i'm on such a kick doing math (i have a test in two and a half hours, wish me luck!) but then i get frustrated trying to convert decimals into roots

and now i'm scrolling tumblr instead

i know i should be doing these calculations by hand and easily getting the fractions, but it's so much easier to enter them into my calculator, then fuck around and write random roots and fractions of them into it until i get the same endless decimals

Statistical Data Types: All You Need to Know

Statistical data is an essential part of any research or analysis. It provides valuable insights and helps us make informed decisions. In this article, we will explore the different types of statistical data and their significance. Understanding these data types is crucial for conducting accurate analysis and drawing meaningful conclusions. I. Introduction Statistical data types refer to the different forms of data that can be collected and analyzed in statistical studies. These data types help us categorize and understand the nature of the information we are dealing with. II. Categorical Data Categorical data includes variables that fall into distinct categories or groups. These variables are usually non-numeric and represent qualitative characteristics. Examples of categorical data include gender, occupation, and marital status. Categorical data can further be classified into nominal and ordinal data. Nominal Data Nominal data represents qualitative variables with no inherent order or ranking. For example, the colors of cars or the types of fruits belong to nominal data. Nominal data can only be categorized and has no numerical significance. Ordinal Data Ordinal data, on the other hand, represents qualitative variables with a natural order or ranking. Examples include movie ratings or levels of education. Unlike nominal data, ordinal data can be ranked or ordered. III. Numerical Data Numerical data, also known as quantitative data, consists of variables with numerical values. These variables can be further divided into discrete and continuous data. Discrete Data Discrete data represents variables that can only take on specific, exact values. These values are usually countable and have gaps between them. Examples of discrete data include the number of people in a household or the number of cars in a parking lot. Continuous Data Continuous data represents variables that can take on any numerical value within a specific range. These values are typically measured and can include decimals or fractions. Examples of continuous data include temperature, height, and weight. IV. Summary Statistics Summary statistics are used to summarize and analyze data. They provide a snapshot of the data set and help in understanding its characteristics. The most common summary statistics include measures of central tendency (mean, median, and mode) and measures of dispersion (range and standard deviation). The choice of summary statistics depends on the type of data being analyzed. For categorical data, the mode (most frequent value) is commonly used. For numerical data, the mean (average), median (middle value), and mode can be calculated. V. Data Visualization Data visualization is an effective way to present and interpret statistical data. Graphical representations help in understanding patterns, trends, and relationships within the data. The choice of visualization depends on the data type. For categorical data, bar graphs are commonly used. They display the frequency or proportion of each category. Bar graphs can easily compare different categories and identify the most common or least common. For numerical data, histograms are commonly used. Histograms display the distribution of values and provide insights into the spread and shape of the data. They can be used to identify outliers or check for skewness. VI. Data Transformation Data transformation involves converting data from one type to another. This can be useful when analyzing data or when certain statistical methods require specific data types. Converting numerical data to categorical data can be done through the process of discretization. Discretization involves dividing the numerical values into range intervals and assigning each value to a corresponding category. Converting categorical data to numerical data can be done through the process of encoding. Encoding assigns numerical values to each category, allowing statistical analysis to be performed. VII. Conclusion Understanding statistical data types is crucial for accurately analyzing and interpreting data. By recognizing the different types of data, researchers can choose appropriate statistical techniques and draw meaningful conclusions. Categorical data and numerical data have distinctive characteristics that require different analysis methods. Summary statistics and data visualization techniques further enhance our understanding of the data. Additionally, data transformation techniques allow for flexibility in working with different data types. By mastering the knowledge of statistical data types, researchers can extract valuable insights and make informed decisions. VIII. FAQs FAQ 1: What are the different types of statistical data? There are four primary types of statistical data: categorical data, numerical data, discrete data, and continuous data. FAQ 2: How are summary statistics used? Summary statistics summarize the characteristics of a data set. They provide measures of central tendency and dispersion, facilitating data interpretation. FAQ 3: What is the purpose of data visualization? Data visualization helps in understanding patterns, trends, and relationships within the data. It provides a visual representation for easier interpretation. FAQ 4: What is data transformation? Data transformation involves converting data from one type to another. It can be useful for analysis purposes or when specific data types are required for statistical methods. FAQ 5: Why is it important to understand statistical data types? Understanding statistical data types is essential for accurate analysis and interpretation. It ensures that appropriate statistical techniques are used and meaningful conclusions are drawn. In conclusion, statistical data types are diverse and significant in any research or analysis. Categorical data and numerical data have distinctive characteristics that require different analysis methods. Summary statistics and data visualization techniques further enhance the understanding of the data. By mastering the knowledge of statistical data types and their analysis techniques, researchers can extract valuable insights and make informed decisions. Read the full article
