They also proposed that a moderator variable D could moderate the effect of A on B, while a different moderator E moderates the effect of B on C. You can use follow up tests to determine whether these simple regression slopes are statistically significant. In our enhanced moderator guide, we show you how to create and interpret a scatterplot to check for linearity when carrying out a moderator analysis using SPSS Statistics and some of the options available to you when you do not have linearity. For this reason, you might often hear this type of analysis being referred to as a moderated multiple regression or as its abbreviation, MMR e. Again, you can learn more about variables in our article: Types of Variable.

The dataset we are going to use is protest. Half of the group got the information that climate change caused the drought, and the other half of the group did not get information about the cause of the drought. Under this approach, one must choose a limited number of key conditional values of the moderator that will be examined. Bootstrapping has also been suggested as a method of estimating the sampling distributions of a moderated mediation model in order to generate confidence intervals.
If the relationship displayed in your scatterplot is not linear, you will have to either run a non-linear regression analysis or "transform" your data, which you can do using SPSS Statistics.
