Question

In a population of n = 6, five of the individuals all have scores that are exactly 1 point above the mean. from this information you can determine that the score for the sixth individual must be ____.

Answer 1

The six scores have to average out to the mean, so their sum has to be six times the mean. Since the sum of the first five is 5 more than 5 times the mean, the remaining score must be 5 less than the mean.

Answer: 5 points below the mean
