Question

Naufal Mohamed · Accepted Answer

It wouldn't be right to say that every one in the group of 100 people have a better IQ. Eventhough the the average IQ is higher than that of the larger population the standard deviation is quite large.

Which means there might be a person in the group of 100 with IQ of 64.5 - 12.5 .
