That is, the IVs are categorical and the DV is numerical. 0 to create bar graphs, histograms, Tukey box plots, line graphs, and scatterplots. An interaction effect represents the simultaneous effect of multiple independent variables on a In a regression model, consider including the interaction between 2 variables when: They have large main effects. The New Terms dialog Want to understand how variables influence each other in a regression model? In this video, we show you how to assess interaction effects (also called moderation effects) in linear regression For mean centering predictors in SPSS, first add their means to your data. Add both predictors, along with the interaction term, something like this: If your interaction (product) term is contributing significantly to the model, then the level of one predictor affects * If you don't have a variable like "group", then you'll need to create it * at this point. I'm interested in how sex and race interact to affect the experience of discrimination in low income health care settings.
