“Bi” means two and the term bivariate analysis refers to the **understanding of the relationship between two variables**. In comparison, univariate analysis is about analyzing one variable, while multivariate analysis refers to understanding relationships between more than two variables.

Bivariate analysis has a lot of use in real life because **it can help understand the strength of the relationship **between the two variables. But before bivariate analysis can define the strength of relationship, it first must define **whether there is any casualty and association between two variables** – whether the value of the dependent variable will change if the independent variable is modified.
