Proc TTest Between two columns

[SasUniversity]

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;
