Quizplus · Accepted Answer

The WAIS test provides a statistical comparison of an individual's raw scores to the raw scores of others in their age group, which is used to determine their IQ score. Option A is the formula used in earlier versions of IQ tests, but not the WAIS. Option C is not a accurate method for calculating IQ as it assumes each question carries the same weightage. Option D is a fictitious set of standards.
