Grouped data for factorial Anova

Troubleshooting

Problem

I am trying to do a 2 * 2 factorial anova using SPSS. Unfortunately, I only have the grouped data (means, SD, N) . I thought that the following syntax should work to produce the results but I get an error message about not having enough SD's (standard deviations). MATRIX DATA VARIABLES=gender group ROWTYPE_ posttest /FACTORS gender group. BEGIN DATA 1 1 MEAN 9.60 1 1 SD 4.461 1 1 N 65 2 1 MEAN 11.04 2 1 SD 3.427 2 1 N 114 1 2 MEAN 11.25 1 2 SD 4.14 1 2 N 121 2 2 MEAN 10.13 2 2 SD 4.23 2 2 N 122 END DATA. MANOVA POSTTEST BY GENDER (1,2) GROUP (1,2) /MATRIX=IN(*) /DESIGN=gender group. I've entered an SD for every group. Why is this not enough?
