Question

Which statement shows correlation but not causation?

students who study longer seem to get higher test scores
eating more vegetables adds more fiber to ones diet
driving more miles requires more gasoline
exercise results in better heart health

Answer 1

The statement that shows correlation but not causation is:

"students who study longer seem to get higher test scores."

This indicates a correlation between studying longer and higher test scores, but it does not prove that studying longer directly causes the higher test scores, as other factors could also be influencing the results.
