SAS Analyst Part 2

First, thank you very much for your comments to my last post, they were very helpful! Second, after I find the differences, which is my independent and which is my dependent variable?? Do I just create a column of all ones and call that my independent variable and then the difference column is the dependent variable?? Thanks!!!!

You said earlier that you had paired data on two independent samples. "Independent" means separable or distinct (like males and females or two drug treatments in a clinical trial), so you should have an indicator variable that demarks the two independent samples.

The dependent variable is the difference score.

If you are looking for a non-parametric ONE-way test of location, then you can do it in SAS/Analyst, but it is a pain in the butt. The test is called a Wilcoxon Signed Rank test (and is part of PROC UNIVARIATE in base SAS). You can read an introductory non-parametric statistics book to see how to do the analysis by hand and then reproduce those steps in SAS/Analyst. You are probably better off using a different tool than SAS/Analyst.
