I am doing some work in SPSS software doing regressions.

Here is the full question: "As a further test of whether WGTPRE, AGE, BODYSAT, SEPHYSACT, SEDIET, MALE, and/or JOBCAT are associated with ENROLL, run a single multivariable logistic regression model using all seven of these potential confounders simultaneously to predict ENROLL."

2 of the variables to be used in this multivariable logistic regression are categorical. Do I need to consider the use of Dummy Variables when doing my analysis?

So far I have just included them all in the analysis with Enroll as the dependent and the seven variables in the other section. Am I on the right track?
