1)During the 1936 presidential election campaign a survey was conducted that predicted Alf Landon would win the election.Roosevelt won in a landslide.The polling sample was gathered from phone book listing and auto registrations around the country.Why do you think the polling failed to predict the election?Why is this question on this exam (the professor is crazy is not an acceptable answer, true but not correct)?Why do you think the present polling is failing in predictions?
