Making Data Management Decisions

# import visulization packages import matplotlib.pyplot as plt # set up the figure size %matplotlib inline plt.rcParams['figure.figsize'] = (20, 10) # make subplots fig, axes = plt.subplots(nrows = 2, ncols = 2) # Specify the features of interest num_features = ['Age', 'SibSp', 'Parch', 'Fare'] xaxes = num_features yaxes = ['Counts', 'Counts', 'Counts', 'Counts'] # draw histograms axes = axes.ravel() for idx, ax in enumerate(axes): ax.hist(data[num_features[idx]].dropna(), bins=40) ax.set_xlabel(xaxes[idx], fontsize=20) ax.set_ylabel(yaxes[idx], fontsize=20) ax.tick_params(axis='both', labelsize=15)

From the histogram, we see that all the values in the variables seem in the correct range. Most of the passengers are around 20 to 30 years old and don't have siblings or relatives with them. A large amount of the tickets sold were less than $50. There are very few tickets sold where the fare was over $500.

BARPLOT FOR THE CATEGORICAL DATA

Next we will create barplots for the categorical variables in the data set. Since "Ticket" and "Cabin" have too many levels (more than 100), I will not make the barplot for these.

# set up the figure size %matplotlib inline plt.rcParams['figure.figsize'] = (20, 10) # make subplots fig, axes = plt.subplots(nrows = 2, ncols = 2) # make the data read to feed into the visulizer X_Survived = data.replace({'Survived': {1: 'yes', 0: 'no'}}).groupby('Survived').size().reset_index(name='Counts')['Survived'] Y_Survived = data.replace({'Survived': {1: 'yes', 0: 'no'}}).groupby('Survived').size().reset_index(name='Counts')['Counts'] # make the bar plot axes[0, 0].bar(X_Survived, Y_Survived) axes[0, 0].set_title('Survived', fontsize=25) axes[0, 0].set_ylabel('Counts', fontsize=20) axes[0, 0].tick_params(axis='both', labelsize=15) # make the data read to feed into the visulizer X_Pclass = data.replace({'Pclass': {1: '1st', 2: '2nd', 3: '3rd'}}).groupby('Pclass').size().reset_index(name='Counts')['Pclass'] Y_Pclass = data.replace({'Pclass': {1: '1st', 2: '2nd', 3: '3rd'}}).groupby('Pclass').size().reset_index(name='Counts')['Counts'] # make the bar plot axes[0, 1].bar(X_Pclass, Y_Pclass) axes[0, 1].set_title('Pclass', fontsize=25) axes[0, 1].set_ylabel('Counts', fontsize=20) axes[0, 1].tick_params(axis='both', labelsize=15) # make the data read to feed into the visulizer X_Sex = data.groupby('Sex').size().reset_index(name='Counts')['Sex'] Y_Sex = data.groupby('Sex').size().reset_index(name='Counts')['Counts'] # make the bar plot axes[1, 0].bar(X_Sex, Y_Sex) axes[1, 0].set_title('Sex', fontsize=25) axes[1, 0].set_ylabel('Counts', fontsize=20) axes[1, 0].tick_params(axis='both', labelsize=15) # make the data read to feed into the visulizer X_Embarked = data.groupby('Embarked').size().reset_index(name='Counts')['Embarked'] Y_Embarked = data.groupby('Embarked').size().reset_index(name='Counts')['Counts'] # make the bar plot axes[1, 1].bar(X_Embarked, Y_Embarked) axes[1, 1].set_title('Embarked', fontsize=25) axes[1, 1].set_ylabel('Counts', fontsize=20) axes[1, 1].tick_params(axis='both', labelsize=15)
