The QQ Plot allows us to see deviation of a normal distribution much better than in a Histogram or box plot.

Does the width (opposite of pointiness) correspond to the width of the normal distribution? This is hard to see on a box plot.Ĭreating a QQ Plot using statsmodels 3.4.

Is the distribution symmetrical (as is the Normal distribution)?.

Having this very fast overview of variables gives us an idea of distribution and as a “bonus”, we get the complete 5-number summary that will help us in further analysis. The boxplot is a great visualization technique because it allows for plotting many boxplots next to each other. The boxplot is a great way to visualize distributions of multiple variables at the same time. The Box Plot plots the 5-number summary of a variable: minimum, first quartile, median, third quartile and maximum. The Box Plot is another visualization technique that can be used for detecting non-normal samples. The histogram is a great way to quickly visualize the distribution of a single variable.
