Mamont248 [21]

Answer:

An incorrect sample frame can destroy a study, regardless of the sample size.

* Timing -- The questionnaires were mailed in early September, they did not measure the changes in public opinions as the election drew closer.

* Self-selection-- It should be understood that an individual cannot select himself/herself into a sample. This is because,the more wealthy and educated do that so the results are entirely accurate
