In this video presentation, Dr. Allwright will once again engage with the multiple linear regression and will add a categorical variable to the model that requires dummy coding. After Dr. Allwright explains the ‘why’ and the ‘how’ of the dummy coding process, she will share multiple dummy coding examples for categorical variables in SPSS. Dr. Allwright will conclude the video with detailed examples of 2 regression models that include dummy variables. Both models will be interpreted at model and variable level, including an explanation on how to properly interpret a dummy variable.
