Question
Suppose you attend a school that offers both traditional courses and online courses. You want to know the average age of all the students. You walk around campus asking those students that you meet how old they are. Would this result in an unbiased sample?
Choose the correct answer below.
A.
No, since this method will not select people who take online classes but may have a different mean age than the traditional students.
B.
No, since students themselves choose to participate in the survey, resulting in response bias.
C.
No, since a relatively large number of students may refuse to respond or lie when asked about their age.
D.
Yes, since this sample is random and samples from the entire population.
Explanation / Answer
A.
No, since this method will not select people who take online classes but may have a different mean age than the traditional students.
