Multiple samples of students were asked four questions, with the sampling variability of their answers to question 4 being the h
ighest. Question 2 had the second highest sampling variability, question 1 came next, and finally, question 3 had the lowest sampling variability. The answers to which of the questions are most reliable?
The variability measures the closeness of the individual data provided. So, the most reliable sampling is the one with the lowest variability.
For this case, the question with the lowest sampling variability is question 3. Therefore, we can conclude that the answers to which of the questions are most reliable is question 3.
