Psychometric Principles and Issues
Users of intelligence tests should have a thorough understanding of statistics, scaling, and measurement principles. The discussion to follow, however, would hardly qualify as “thorough.” This chapter is merely a reminder of what students have already covered in previous course-work that is central to the use of intelligence tests. It is assumed that the user of this text has had, at a minimum, undergraduate courses in statistics and tests and measurement. If a user of this text is not acquainted with some of the principles discussed here, then a statistics and/or measurement textbook should be consulted. There are a number of excellent measurement textbooks available including Anastasi and Urbina (1997).
