Linear regression is the most basic and commonly used predictive analysis. Regression estimates are used to describe data and to explain the relationship between one dependent variable and one or more independent variables.
Step 2: Check for linearity. One of the fundamental assumptions of regression analysis is that the relationship between the dependent and independent variables is linear (i.e., the relationship can be illustrated with a straight line.) One of the quickest ways to verify this is to graph the variables using a scatter plot.
