1. For the Experiment 2 data analyzed as a two independent-groups design as in Exercise 11, characterize the magnitude of the effect in the following ways: a. As a standardized difference between means, d. b. By computing the following measures of the proportional reduction in error: R2 and &>2. 2. For your master’s thesis you are doing a study that in part replicates previous research. You plan to use three groups and expect the means on the dependent variable to be 55, 67, and 79. On the basis of previous research, you have evidence that leads you to expect the population within-group variance to be about 3600.
