Question

In a sample of n = 8 scores, seven of the scores are each above the mean by one point. Where is the eighth score located relative to the mean?

a) It is one point below the mean.
b) It is at the mean.
c) It is one point above the mean.
d) It is two points above the mean.

Answer 1

The eighth score is one point below the mean.

Step-by-step explanation:

The mean is the average of a set of numbers. In this case, the mean is the average of the eight scores.

Since seven of the scores are each above the mean by one point, this means that the mean is one point below the seventh score.

Therefore, the eighth score is also one point below the mean, so the answer is a) It is one point below the mean.
