a.
Explanation of Solution
Factorial Research Design:
A factorial research design is used for testing the effect of two or more grouping variables at a time by considering the groupings of every combination of the variables.
b.
Give one advantage of a factorial research design over doing two separate studies.
b.
Explanation of Solution
One of the advantages of factorial research design is efficiency. That is, in the factorial research design, the effects of two grouping variables are examined at a time by considering only a single group of participants.
c.
Give another advantage of a factorial research design over doing two separate studies.
c.
Explanation of Solution
One of the advantages of factorial research design is identifying the possibility of interaction effects between the groupings.

The distribution is most likely skewed to the left, and the mean is less than the median. The distribution is roughly symmetric with a few high outliers, and the mean is approximately equal to the median. The distribution is most likely skewed to the right, and the mean is greater than the median.
