Question

A research worker plans to evaluate high school students' reactions to a new policy on cafeteria food. He locates himself near the office of the principle, where he interviews every fourth student who visits the dean. He eventually secures data from 100 interviews and publishes his findings as the "Reactions of high school students to a new policy food policy." What may be wrong with this approach? Too small a sample Inadequately defined problem Inadequate techniques of analysis Biased sample

Answer 1

Answer: The third statement

Explanation: The techniques he employed to use is were a possible fault could occur. Because the principle office is not were every student of the school would go and not every 4th student that enters the office would represent the same thing of what other students are saying. I believe the technique used might be wrong. I would employ that he should consider going to the cafeteria and do some research on the policy and see at first hand the reaction of the students than the principle office.
