Question

Quizplus · Accepted Answer

The T score is based on the normal distribution and is used to standardize raw scores. Therefore, it can only be used when the distribution of scores is normal. Choices A and C are incorrect because the mean of the raw score distribution can vary and does not have to be 50 or 100 in order to use T scores. Choice B is incorrect because the T score is based on the normal distribution, not the z score distribution.
