Question

To determine whether voters would be willing to vote for a tax increase to improve the city's schools, the board of education surveys 500 parents of children in the city's schools.

Why is this sample likely to be biased?

A.The entire population of the city was not surveyed.

B.Parents of school children are too busy to be bothered with surveys.

C.There are not enough people in the sample.

D.Parents of school children are more likely to be willing to pay more to improve schools.

Answer 1

B.

This is because, the people who conduct the survey and came to the conclusion of B are making an assumption that they are too busy. This is biased because from the point of view of THEM or even the education board, this could be manipulated in such a way that is not factual.

So in a nutshell, B is bias because it is not 100% factual. Remember, it's all about perspective.
