How to Create a Scatter Plot Graph in SPSS

A scatter plot displays the nature of the relationship between two variables. Before performing a regression analysis, it is recommended to run a scatter plot to determine if there is a linear relationship between the variables. If there is no linear relationship (i.e., points on a graph are not clustered in a straight line), there is no need to run a simple regression.
