Bivariate analysis

Bivariate analysis is typically the next step you would take after single variable analysis. Bivariate analysis is used to show the relationship between any two variables. You are performing bivariate analysis for two reasons:

• In a modeling framework, one key outcome we are looking for would be any association between the target variable and any one of the independent variables.
• Another, equally important outcome we are looking for is any possible associations between any two of the independent variables. That will help us understand which of the independent variables are correlated with each other, or help us understand how one variable changes the behavior of another.
