Simply put, a dummy variable is a Nominal variable that can take on either 0 or 1.

This was broken into 3 categories (to make equally sized groups) creating the variable mealcat.Д«efore we begin, we need to clarify what a dummy variable is (itвЂ™s actually rather smart!). The variable meals is the percentage of students in the school who are receiving state sponsored free meals and can be used as a proxy for socioeconomic status. The variable yr_rnd is a Nominal variable that is coded 0 if the school is not year round and 1 if year round. Recall that the variable api00 is a measure of the school academic performance. We will continue to use the elemapi2v2 data set we used in Lessons 1 and 2 of this seminar. Other than Section 3.1 where we use the REGRESSION command in SPSS, we will be working with the General Linear Model (via the UNIANOVA command) in SPSS.

#SPSS 16 FOR DUMMIES HOW TO#

This lesson will show you how to perform regression with a dummy variable, a multicategory variable, multiple categorical predictors as well as the interaction between them. A regression with categorical predictors is possible because of whatвЂ™s known as the General Linear Model (of which Analysis of Variance or ANOVA is also a part of). Nominal and categorical variables are used interchangeably in this lesson. However, it is possible to include Nominal predictors in a regression analysis, but it requires some extra work in properly interpreting the results.

In the previous two lessons, we focused on regression analyses using Scale predictors.

3.5 Regression with the interaction of two categorical predictors.

3.4 Regression with two categorical predictors (main effects model).

3.3 Regression with a 1/2/3 (multicategory) variable.

3.1 Regression with a 0/1 (dummy) variable.
