In the Upper Two Standard Deviation Approach, When You Employ

Multiple Choice

In the upper two standard deviation approach, when you employ SPSS to compute the standard deviation of a set of scores, the way to determine whether your treatment mean is significantly better than the baseline mean is:

A) compute the baseline mean and the treatment mean. Double the standard deviation and add it or subtract it from your treatment mean to determine whether your treatment mean is significantly better than the baseline mean
B) compute the baseline mean and the treatment mean. Double the baseline mean and add it or subtract it from your treatment mean to determine whether your treatment mean is significantly better than the baseline mean
C) compute the baseline mean and the treatment mean. Double the treatment mean and add it or subtract it from your baseline mean to determine whether your treatment mean is significantly better than the baseline mean
D) compute the baseline mean and the treatment mean. Double the standard deviation and add it or subtract it (as indicated by the nature of the change desired in the outcome variable) from your baseline mean to determine whether your treatment mean is significantly better than the baseline mean
