Summarizing Change in Test Scores: Shortcomings of Three Common Methods.
Russell, Michael
Practical Assessment, Research & Evaluation, v7 n5 2000
Discusses the advantages and disadvantages of three commonly used methods for summarizing change in test scores: (1) change in percentile rank; (2) scale or raw score change; and (3) percent change. In general, these methods are insensitive to the measurement scale on which scores are expressed and perform mathematical operations that are inappropriate for these measurement scales. (SLD)
