c. What are the independent and dependent variables depicted in the graph? What kind of variables are they? If nominal or ordinal, what are the levels?

d. List at least three things that the graph creators did well (i.e., are in line with the guidelines for graph construction).

e. List at least one thing that the graph creators should have done differently (i.e., is not in line with the guidelines for graph construction).

f. Name at least one variable other than number that might be used to track the prevalence of psychology bachelor's, master's, and doctoral degrees over time.

g. The increase in bachelor's degrees over the years is not matched by an increase in doctoral degrees. List at least one research question that this finding suggests to you.
