In SAS, PROC MEANS is used when you want to calculate descriptive statistics for one or more numeric variables. You might choose PROC MEANS over PROC FREQ (which is used for frequency analysis) if your data primarily consists of numerical values and you want summary statistics such as mean, median, range, standard deviation, etc.

Have you ever used the SAS Debugger?
