Jose hypothesizes that a new drug he has just invented will enhance mice’s memories. He feeds the drug to the experimental group and gives the control group a placebo. He then times the mice as they learn to run through a maze. In order to know whether his hypothesis has been supported, Jose would need to use

(A) scatter plots.
(B) descriptive statistics.
(C) histograms.
(D) inferential statistics.
(E) means-end analysis.

Answer
(D) inferential statistics.

Spoiler
Explanation
Jose needs to compare the performances of the two groups using inferential statistics to determine whether or not the experimental group’s performance was significantly better. Scatter plots are used to graph correlations. Jose would certainly be interested in descriptive statistics as well, but he would not know whether or not his hypothesis had been supported until he used inferential statistics. Histograms are bar graphs, and means-end analysis is a problemsolving technique.
