1. Identifying main effects and interaction The results of a two-factor, independent-measures, equal n experiment are summarized in the following matrix. The numerical value in each cell is the mean score obtained from the sample in that treatment condition. Compute the overall means for the scores in A1, the scores in Az, the scores in B1, and the scores in Bz. Enter each of the means to the right of the appropriate row or below the appropriate column in the matrix. A₁ Az B₁ M=6 M = 4 M = B₂ M = 4 M = 2 M = M = M =
