Question

suppose that there were a strong correlation between the variables g and h. which of these is a true statement? a. g may cause h. b. h must cause g. c. g must not cause h. d. g must cause h

Explanation:

Correlation does not imply causation. Just because there is a strong correlation between \(g\) and \(h\), it is possible that \(g\) causes \(h\), \(h\) causes \(g\), there is a third - variable causing both, or it is just a coincidence. Options B, C, and D use “must” or “must not” which are too absolute. Option A uses “may” which is appropriate as correlation allows for the possibility of causation (but does not prove it).

Answer:

A. \(g\) may cause \(h\)
