Luc randomly selected 40 students and asked them whether they had ever gone snowboarding. He repeated this survey using the same

method three more times.
Do any of the surveys appear to be biased?

Ever gone snowboarding? Survey
1 2 3 4
Yes 10 13 2 12
No 30 27 38 28


A.
Yes, because the results from Survey 3 differ significantly from results from Surveys 1, 2, and 4, which agree.

B.
Yes, because all four surveys do not have identical results.

C.
No, because although the results differ among the four surveys, the sample method used for all was the same.

D.
No, because all four surveys have about the same number of people saying “yes” and about the same number of people saying “no.”

<span>C. No, because although the results differ among the four surveys, the sample method used for all was the same. Luc RANDOMLY selects 40 students in every survey. Random selection in surveys do not create bias and the results are highly credible. This is because there are no preconceived notions or factors that affect the responses of people being surveyed.</span>
