Hi! I need to solve the following question: Do anthropometric and fitness variables predict the difference between being in the top quartile of improvement in jumping height between year 1 and year 6 or not being in the top quartile? Reduce the number of anthropometric and fitness variables before doing the analysis. Given is a dataset with different variables (see attachment) I was wondering which steps I need to take to solve this problem?

Thanks in advance if anyone could help me! I am using version 7.1 of Sas Enterprise Guide.
