5 Performing Bivariate Analysis in Python

Bivariate analysis uncovers insights embedded within two variables of interest. When performing this analysis, we are typically interested in how these two variables are distributed or related. Bivariate analysis can sometimes be more complex than univariate analysis because it involves the analysis of categorical and (or) numerical values. This means that in bivariate analysis, we can have three possible combinations of variables namely: numerical-numerical, numerical-categorical, and categorical-categorical.

It is important to understand the various chart options that cater to these combinations. These chart options can help us understand the underlying distribution of our data and identify any hidden ...
