· First, perform a pre-evaluation of the data for outliers (all variables) and normal distribution (only dependent variables) as you have done previously.

· Then, useHow to Choose a Statistical Test (linked in Resources) as general guidance in helping you to decide which test to use.

· Use the readings, media, resources, and textbook as guides to perform an analysis of the selected variables.
