Hello,

 

I appreciate anyone can help - I am looking for an appropriate test to "compare means of 3 different groups in a prospective data"

 

data wide; 
input id hand06 hand07 hand08 hand09;
cards;
1 40 32 . 35
2 26 34 . 39
3 39 41 . 47
4 36 50 . 41
5 42 38 . 39
;
run;

proc means data=wide fw=8;
var hand06 - hand09;
run;

 

data long; set wide;
year=06;
hand_=hand06;
output;

year=07;
hand_=hand07;
output;

year=09;
hand_=hand09;
output;

drop hand06-hand09;
run;

 

proc means data=long;
class year;
var hand_;
run;

ANOVA is a starting point. Make sure to visually inspect the data and do some histograms.

Thank you - I agreed.

Beside the ANOVA, is there any test.
