Question

A polling organization surveys 75 people skating in a skate park on a Saturday to determine whether town residents approve of the president's job while in office. What type of bias does this sampling method produce?

A. Non biased
B. Convenient
C. Volunteer
D. Random

Answer 1

B. Convenient is your best answer

Explanation:

The Polling Organization may think that the skate park is the best place to survey because there may be a large body of people (75+) that can give their opinions.

It is not A, because all opinions are biased.

It is not C, because the people themselves are not volunteering.

It can be D, but it is not all that random.
