In this chapter, the authors will discuss the following types of standard scores: percentile ranks, z-scores, and T-scores. All are based on concepts—such as the mean, the normal distribution, and the standard deviation—already familiar to you from the last two chapters. In the case of class rank, however, keep in mind that a percentile rank from an ordinal scaled score should be used.
