Then, in the New Value side, enter 1 for the value. So, in the Old Value side, enter 2 for the value. Now, change the Name and the Label to Dum1, and click on Change.Īnd we’re going to want those in Group 2 to have a value of 1. Now, click on Groups, and then click on the highlighted arrow to move Groups to the empty window. To do so in SPSS, we should first click on Transform and then Recode into Different Variables.

In this case, we will make a total of two new variables (3 groups – 1 = 2). To perform a dummy-coded regression, we first need to create a new variable for the number of groups we have minus one. The instructions below may be a little confusing if your data looks a little different. If your dataset looks differently, you should try to reformat it to resemble the picture above. The data should look something like this: In the dataset, we are investigating the relationships of three training groups and conscientiousness with sales.

If you don’t have a dataset, you can download the example dataset here. To answer these questions, we can use SPSS to calculate a regression equation. Of course, there is more nuance to dummy-coded regression, but we will keep it simple.

Believe it or not, a linear regression can also identify the differences between groups pretty well – as long as we know how to code our predictors correctly. As always, if you have any questions, please email me at typical type of regression is a linear regression, which identifies a linear relationship between predictor(s) and an outcome. This page is a brief lesson on how to perform a dummy-coded regression in SPSS. To do this, dummy-coded regression can help out. Typically, I tell students that the two primary categories of “basic” statistics is whether they (a) determine the relationship between things or (b) the differences between groups.
