What change would you make in the survey or in how the survey is
administered in order to increase the survey's validity? Remember
that validity asks the question: "Are you measuring what you
intended to measure?" What third variables might there be that
would cause a spurious correlation in the survey results? Note: a
spurious correlation involves relationships in which two events
have no causal link, but still appear to, due to either a
coincidence or a third, confounding variable....
