"There are two possible outcomes: If the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery."
Enrico Fermi, physicist and Nobel laureate (29th September 1901-1954)

Statistical Significance
Statistical significance is a key concept in research and data analysis, representing the likelihood that a result or relationship observed in a study is not due to random chance. In hypothesis testing, a result is considered statistically significant if the p-value falls below a pre-determined threshold (commonly 0.05), indicating strong evidence against the null hypothesis. This concept helps researchers determine the validity of their findings and ensure that conclusions drawn from data have a low probability of being due to random variation.

What is Exploratory Data Analysis? Everything you need to know
They often rely on data visualization methods to spot patterns, identify anomalies, test hypotheses, and check assumptions. EDA is a great way to find out what data can reveal beyond formal modeling and hypothesis testing and get a better understanding of data variables and their relationships.

Statistics 101: Hypothesis Testing
Tumblr media
Hypothesis testing is a method used in Inferential Statistics to observe a small section of the population called a sample, in order to draw insights that can tell us about the population at large. Hypothesis testing forms the very foundation of statistical analysis, to the point where the main purpose of learning statistics is so that we can perform hypothesis testing. Take for example, your friend suggests a great place to order. Now if there is some basis to why he or she said that, which can be used to identify other great restaurants, then and only then would it be useful. If not, we would probably just be “tasting” by fluke.
So, what is a hypothesis? Put simply, it is a calculated guess about something in the world around us based on an inference or insight drawn from an observation. Ofcourse, this should be proven and thus, we perform hypothesis testing which we’ll soon learn more about. For now, let’s take a look at what hypothesis looks like:
Whether a drug would qualify as a corona virus vaccine. Likelihood of discovering gold or lithium in a certain location. Recovering with quality drugs can prevent fatigue in football players before the next match. Increasing the level of hatha yoga practice leads to higher levels of psychological well being. Two types of hypothesis tests: z-test and t-test In order to prove a statement or test out hypothesis broadly, let’s now see the two main types of tests. These are called the z-tests and t-tests. More often than not, practical purposes use t-tests because they use a sample’s standard deviation instead of z-tests which use a population’s sample deviation. While it is ironic for us to perform tests if we already know about the population at large, z-tests are easier to understand before moving on to t-tests since they can help relate to concepts such as normal distribution as well. This is because z-tests work best when the sample size is generally more than 30, unlike t-tests which give the same result more or less as the sample size goes on increasing.
Now before we get into the depths of performing statistics, we have to choose the test required for our hypothesis. In order to do so, we collect data and look at the samples. For z-test, we can further choose to perform between one sample z-test or two sample z-test. A one sample z-test is performed when we have to analyse one group with a given population mean whereas a two sample z-test is performed when we are comparing the means of two different sample groups. Both these types of tests fall under the t-tests as well, however, we can also conduct a paired two sample t-test where both groups can be analysed basis of different time of occurrence.
Examples: We perform one sample z-test to find out whether the students of a certain school are performing better than the entire population of students of other schools. However, we perform a two sample z-test to find out whether the students of a certain school are performing better than the students of other schools.
Now for a paired t-test, we can find out whether the students of a certain school are performing better than the students who graduated 5 years ago. Null hypothesis and alternate hypothesis Now before we start performing analysis, it is important to state the null and alternate hypotheses so that we can round off our findings with a conclusion. A null hypothesis is generally accepted for its factual consistency, something we can validate or reject based on our findings. Let’s say - the average score of students appearing for the whole exam is x. A null hypothesis, denoted by H0, can be set as this average score for comparison with the sample of students appearing in the exams now. For this, our hypothesis that this batch of students is better than ever before stands true if an alternate hypothesis is better than the null hypothesis. An alternate hypothesis, denoted by H1, can now be more or less than the mean values set in the null hypothesis. If the result is true, null hypothesis is rejected and our findings can be corroborated with evidence. Now, let’s sum up the hypothesis testing with 5 simple steps that we use to perform experiments using observations. 5 steps of performing hypothesis testing State the null and alternate hypothesis Collect data samples Choose which test to perform Decide whether to reject or accept your null hypothesis Present your findings Conclusion: With hypothesis testing, you can now increase the likelihood that the restaurant you choose over your next date or family dinner is going to be worth it! You can confidently set up a good time and space.. Because of hypothesis testing! How? Simple. Collect data samples about restaurants and cross check with general user reviews, or compare maybe a chinese restaurant with other restaurants offering a similar menu to your liking. This is how apps use data to provide suggestions, however, hypothesis testing can be used across a diverse range of industries.
If you’re interested in learning more about hypothesis testing, statistics or everything under the sun called Data Science, we highly recommend that you speak to one of our counselors. Why we make a strong recommendation is because after enrolling for a course at Skillslash, you also get certified real work experience at top MNCs upon completion.

I’d been avoiding reading nobody nothing nowhere because of the tags, but finally gave it a go after you rec’d it and holy shit that was a fucking depressing read, but it was very good and I don’t know how to feel about it now
Yeah the tags are very accurate, which is good because NNN won’t be most people’s cup of tea. After I finished my first read I felt compelled to go through some Aemond/Luke scenes again with new eyes, which was nice…but even for me I needed to find a fluffy/smutty fic soon after and probably won’t ever do a full reread 💀
All credit goes to @goodbadbaby for making us feel so many things with just the power of prose! A standing ovation is in order! And maybe group therapy for all the readers 😂😂😂

I can kind of see Luke taking his “power” as far as he can. Like getting to the point where he’s asking Aemond to bottom for him. Whether Aemond would ever get to that place remains to be seen (you’ve said one of the things primary to this Aemond is we can’t get into his mind). I picture Luke probably coming as soon as in that position due to his “he’s nothing without me” line of thought we have seen this chapter (I’ve summarised that terribly you wrote it way more compelling but I can’t fit Luke’s state of mind into a 4 word sentence I’ll leave that to the professionals (you!)).
If he got to the point where he’s got Aemond to the point in his fake love routine to open up his “cunt” willingly, it would probably be his greatest achievement in his now fucked up mind lol.
Knowing how Jealous Aemond was of Sel I can see him thinking well Luke doesn’t need pussy he’s got mine. Because again, he’s delusional !
Unfortunately luke coming from the power trip would probably convince Aemond he has crazy throw back power and rules Luke with his ass and dick and I don’t want that for him haha. Picturing Luke’s reaction to Aemond thinking HES the one being manipulated with sex is hilarious though 😂😂.
This is probably so duh but I think Luke has really been conditioned to see sex=power which is obviously a symptom of his abuse. How he’d go about having healthy sexual relationships in the future (even with women!) puzzles me. I don’t know if you read the fic nobody, nothing, nowhere by hypothesistest but it also plays the abuse quite straight too and focuses on the impact it has on Luke and is one of my favourite fics on the subject matter with how it explores how the abuse affected Luke long after it was over and in what ways his abuse reared it’s head (which I can see in your excerpt you posted today!) during his everyday life and his attempts at intimacy. I’m really looking forward to the sequel for this reason and it will NOT be a skip for me! I love your Luke for who is not his bussy!!
If Luke did ever make it back to his family how do you think he would go back to being Rhaena’s bethrothed or Rhaenyra’s “good boy”. Especially if Jacegan is canon in your views. One brother experiencing the joys of bottoming with the man he swore a blood oath to up north after building a relationship through hunting and drinking and friendship versus the other experiencing it as this shameful reaction from his body that makes him unworthy and had brought so much pain on a physical and psychological level!
The irony of Jace going to a secluded castle during war time and being the one with the healthy sexual experience versus Luke going from an argument with his uncle
Just Luke whump all around!
I haven’t read this fic since December?? I think but you being back has got me on theories galore! Please let me know if you don’t like this kind of in depth q&a’s for your fics and I’ll stop no harm done! I’m just usually question question question about character dynamics!
Thank you very much for listening to my delusions I just like your work a lot haha
some more, slightly more spoiler-y stuff
"he’s nothing without me" summarises it pretty well. Aemond tried to make himself the centre of Luke's life & in the process made Luke the centre of his, oops. Luke didn't ask to be part of this dynamic, but if they're going to be stuck in each other's gravity he's certainly going to use it to whatever advantage he can. which definitely means making power plays via fucking (as you point out, this whole thing has taught him power=sex, which already is an idea pretty present in Westeros). i may have to break out the switch! tags for Hand for Hand.
('may'. i already have a pretty strong (ha) idea for how bottom!Aemond is going to make it's appearance in the plot)
i hadn't read the fic nobody, nothing, nowhere by hypothesistest, but thank you for the rec because i went & devoured it today. really great psychological stuff. based on it, i don't think you'll be disappointed by what i have planned for Tooth for Tooth. strangely, the lucemond dynamics in nobody, nothing, nowehere -- the only one able to understand what the other has been through -- feels like the cousin to the darker, more fucked up lucemond dynamics i have planned for hand for hand. nobody, nothing, nowhere did actually manage to make me regret for a second not writing a more wholesomely co-dependent lucemond. for a very loose definition of wholesome. because them getting to heal together was an amazing ending to read. unfortunately, the Aemond in lflfefe isn't a fellow victim but the abuser (Aegon, meanwhile, has two for two going on the rapist front). i do plan for Rhaena to have a small part in Tooth for Tooth, and a larger part in Hand for Hand. i won't say more, except to thank you for the reminder that fleshing out some non-Luke relationships might be worthwhile. i mean, personally, i think Luke should be the centre of all relationships -- romantic, platonic, familial -- but apparently having everything be in relation to just one character can make it hard to 'flesh out themes' or 'build the narrative' smh. (side tangent, but i read the Locked Tomb series this year & that had fucking amazing side character/relationship work, so definitely something i want to practice!) you make a good point that jacegan could have some very juicy parallels. thank you for the ask(s)! it's amazing having someone care this much about the character dynamics in something i wrote. fanfic as a medium has very different rules & conventions to, say, novel as a medium, but for me, even as i'm being self-indulgent, LFLEFE (& Deuteronomy 19-21) is a place where i'm cutting my teeth in regards to character work, relationship dynamics, plotting, etc. and also just finishing a piece of writing (even if it takes years). so it's very validating to have someone analyse & theorise like this! based on the ask(s) i think there's quite a few things you'll enjoy if i stick to my current outline ;)
