text: There does seem to be a correlation between homework and standardized test scores, but (a) it isn’t strong, meaning that homework doesn’t explain much of the variance in scores, (b) one prominent researcher, Timothy Keith, who did find a solid correlation, returned to the topic a decade later to enter more variables into the equation simultaneously, only to discover that the improved study showed that homework had no effect after all, and (c) at best we’re only talking about a correlation -- things that go together -- without having proved that doing more homework causes test scores to go up.
