Question

IQ scores have a mean of 100 and a standard deviation of 15. Nick has an IQ of 112. What is the difference between Nick's IQ and the mean?

Answer 1

Nick's IQ is 12 points above the mean IQ score, since the mean IQ score is 100 and Nick's IQ score is 112.

Step-by-step explanation:

The difference between Nick's IQ and the mean IQ can be found by subtracting the mean IQ score of 100 from Nick's IQ score. Since Nick has an IQ of 112, we calculate the difference as follows:

1. Identify the mean IQ score, which is 100.
2. Identify Nick's IQ score, which is 112.
3. Subtract the mean score from Nick's score: 112 - 100 = 12.

Therefore, Nick's IQ is 12 points above the mean IQ score.
