RIght now, I'm trying to run a t-Test in sas (or rather a WMW test) but the variables are two different columns rather than two treatments under the same column.
I.e. instead of something like this:
Method Grade
c 80
c 93
c 83
c 89
c 98
t 100
t 103
t 104
t 99
t 102
I have something like this:
c t
80 100
93 103
83 104
89 99
98 102
Is there anyway to run a WMW test on data that looks like the second case?
Is your current data such that it is actually paired? That the C=80 and t=100 should be considered such as a before/after or other natural pairing? Then Proc Ttest with Paired c*t would be natural.
Otherwise it might be that transposing the data would be appropriate.
data want;
set have;
method = 'C'; value=c;output;
method = 'T'; Value=t;output;
keep method value;
run;
proc ttest data=want;
class method;
var value;
run;
