Question
Two independent surveys asked random samples of 500 people about the distances they commute to work each day. The results of the surveys are detailed in the table below.
Which statement is true based on the results of these surveys?
- There is a greater variation in the distribution of the distances people commute to work in Survey A.
- There is a greater variation in the distribution of the distances people commute to work in Survey B.
- The variation in the distribution of the distances people commute is the same in both surveys.
- It is impossible to determine the variation in the distribution of the distances people commute because the means are different.
The correct answer is: The variation in the distribution of the distances people commute is the same in both surveys.
Since, the standard deviation same. The variation will be equal.
