Further Explanation:
<u>The Literary digest polls had always predicted right winner for the president through it polls before year 1936.</u> They predicted every president correctly in their pools for 1920 elections, 1924 elections, 1928 elections and 1932 elections.<u> But their prediction for 1936 elections was wrong by 19%. in 1963, they polled over 2 million of its subscribers by sampling them</u> and asking them to send their samples back and on the bases of that poll they declared Alf London to win the elections but what happened was a complete reverse as Roosevelt won the elections convincingly. After the final election results were out, Literary digest was thrashed by readers for its wrong prediction. But what went wrong for them?. After reviewing the cause of this failure, they found out that the two million people they polled as samples were not representatives of majority of Americans as period of ‘Great Depression’ was going on in America. <u>The subscribers of digest was also wealthier then rest of American people as subscription of the Digest was costly. Subscribers of the Digest owned telephones and cars but on the other hand people who voted for Roosevelt belonged to poor class.</u> So the learning outcome from this was a survey has to conducted among every class of people to get better pre-poll survey result.
