Explaining Behaviors: Crime Reduction

APSTAT-YTPELW

A recent study found that people who exercise at least $4$ times a week are less likely to have a criminal record than those who do not exercise at all.

This fact could be explained by

A

Simple coincidence since exercising has nothing to do with crime involvement.

B

Some other type of common response or confounding variable.

C

A possible causal link between exercise and lack of a criminal record.

D

A flaw in the implementation of the experiment.

E

Nothing; since this was an observational study, no real linkage can be made between exercise and criminal activity.
