Hi all, Thanks for all those messages !!! I really appreciate the time and help of those who post a reply to questions posed .. I conclude that my case is a repeated measures design with repeated measures on factors fit and finish.. Which is the best way to enter the data in spss ?
i have 5 columns column1 col2 col3 col4 col5 Subject med_w/o finish large_w/o fin med_w/fin lar_w/fnsh 1 . . . 8 And i go to GLM -> Repeated measrues -> Within factor (fit-2 and finish-2) Is this the right step?? should i add anythign in the "between subjects column"?? Please let me know about this..
