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,

Re: getting the mean in longitudinal observations

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