What is the value of ΣX + 1 for the following scores?  Scores: 1, 6, 3

A set of n = 25 pairs of scores (X and Y values) has a Pearson correlation of r(23) = .60. How much of the variability among the Y scores is predicted by the relationship with X?

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)?

Using the chart below, calculate SP. X Y 7 6 10 6 7 9

What is the value of Σ(X + 1) for the following scores?  Scores: 1, 0, 1, 4

What is the value of ΣX + 1 for the following scores?  Scores: 1, 6, 3

Calculate the regression equation with the following information: SP = 101.43, SSx = 154.56, My = 11.52, and Mx = 12.13

What are the possible values for a Pearson correlation coefficient, r?

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?

The following data represent the means for each treatment condition in a two factor experiment.  Note that one mean is not given. What value for the missing mean would result in no main effect for factor B?                 B1         B2       A1    20    10     A2    40     ?
