Answer to Question 1

In the Bond et al. study, they found that boys showed less depression as a result of bullying. However, the attrition rate for boys was larger than for girls. This might mean that boys who were affected by the bullying by becoming depressed may have dropped out of the study, whereas boys not so affected did not drop out. It would have distorted the effect of bullying on boys.
Further, there was more attrition for students from single-parent families. Perhaps people in such families are differentially susceptible to depression than are students from two-parent (or other) families.

Answer to Question 2

(a) Groups should be equivalent with respect to the DV at the start of the study.
(b) There should be no confounds or extraneous variables.
(c)) The IV and the DV should show construct validity.
