That's a bit clearer. Thanks. On the understanding that the first, second, ... observation contain information for 0, 1, ... mentions gen wt = _n - 1 su j? [fw=wt] Nick n.j.cox@durham.ac.uk Aggie Chidlow Dear Nick (and others), Sincerely Appologies. It is not my intention for you to do any guess work... I am working on a meta-analysis the data I have looks like this: All Data Collection | Name of the journal the article appeared Procedures together | J1 J2 J3 J4 | Total Not Mention | 68 41 32 25 | 166 One Step mention | 17 14 17 12 | 60 Two Steps mention | 8 9 8 5 | 30 Three Steps mention | 4 5 2 6 | 17 Four Steps mention | 1 2 1 1 | 5 Five Steps mention | 1 0 0 0 | 1 ----------------------+--------------------------------------------+---------- Total | 99 71 60 49 | 279 Today, it was suggested to me that I could calculate the mean number of mentions, within each of 4 journals and then perform metan to calculate a weighted average mean across the 4 journals. In order to do this I have to transpose the data from the table above to this: Data Collection Procedures j1 j2 j3 j4 total > Not Mentioned 68 41 32 25 166 > One Step Mentioned 17 14 17 12 60 > Two Steps Mentioned 8 9 8 5 30 > Three Steps Mentioned 4 5 2 6 17 > Four Steps Mentioned 1 2 1 1 5 > Five Steps Mentioned 1 0 0 0 1 I am stuck at this point, because I am struggling to figure out how to calculate the mean number of mentions with their standard errors for this data.
