In this video presentation, Dr. Allwright will again engage with the multiple linear regression inferential test, but this time for the purpose of a full diagnostic statistics, also known as testing assumptions. Dr. Allwright will explain the assumptions of the diagnostic statistics with great detail, address why the fulfillment of the assumptions are important, and how to test for each assumption. Dr. Allwright will present an example of a multiple linear regression model in SPSS with dummy variables and run a full diagnostic to evaluate all assumptions. As always, Dr. Allwright will deliver a full interpretation of the model and tell the full story of the data.
