For a two-factor study with 2 levels of factor A, 2 levels of factor B, and a separate sample of 10 participants in each treatment condition, the two means for level A1 are 4 and 1, and the two means for level A2 are 3 and 2.  For these data, what is the SS value for factor A (SSA)?

Two samples from the same population both have M = 84 and s2 = 20; however, one sample has n = 10 and the other has n = 20 scores.  Both samples are used to evaluate a hypothesis that µ = 80 and to compute Cohen’s d.  How will the outcomes for the two samples compare?
