https://communities.sas.com/t5/SAS-Procedures/groups/m-p/10034#M869 My surveys requires over 5,0000 interviewees rank two conditions <BR /> separately from 1 to 10. I wish to assign interviewees into 10*10 = <BR /> 100 groups such as group (1,1), the group that interviewees rank both <BR /> conditions 1 or group (1,2), the group that interviewees rank the first <BR /> condition 1 and the second condition 2 etc. <BR /> Do you know any way to help me out? <BR /> what happens if we rank three conditions?<BR /> Based on the group, i wish to do statistics such as mean, median, standard deviation, t-test for the diffrent between groups. <BR /> Thank you so much for your help, Fri, 30 Oct 2009 22:43:43 GMT deleted_user 2009-10-30T22:43:43Z https://communities.sas.com/t5/SAS-Procedures/groups/m-p/10034#M869 My surveys requires over 5,0000 interviewees rank two conditions <BR /> separately from 1 to 10.

As you're having balanced data I believe it's Proc ANOVA you're looking for.<BR /> <BR /> <BR /> HTH<BR /> Patrick Sat, 31 Oct 2009 07:18:02 GMT https://communities.sas.com/t5/SAS-Procedures/groups/m-p/10035#M870 Patrick 2009-10-31T07:18:02Z
