getting the mean in longitudinal observations

Hi,

How do I get the mean between observations in a longitudinal dataset?

I have the following:

ID Measurement

1 10.02

1 9.96

1 8.24

1 7.56

1 6.94

2 3.23

2 4.55

2 5.78

2 7.89

2 6.32

3 4.21

3 7.89

3 8.94

3 10.55

It is basically transforming the data from longitudinal to non-longitudinal.

Many thanks,

Have you tried PROC MEANS? SUMMARY or UNIVARIATE or SQL will also work.
