Question

When a 1936 Literary Digest poll found overwhelming support for Alfred Landon’s presidential bid over Franklin Delano Roosevelt, they made an erroneous prediction that Landon would defeat FDR. What are the probable sources for error in their poll that helps explain their mistake?
a.Non-response rate was highb.Sample was not representative of the population
c.Failed to use probability sampling techniques
d.All of these

Answer 1

The correct answer is letter D

In this situation what occurred was a section of errors while counting probable votes, such as non-response rate, the sample did not match the population, as well as the probability skills that were flawed. In research it is very simple to make mistakes so it is necessary to have people who are good at doing this work.
