Selecting a grade with the most (or least) overlapping in assessment categories It is a common practice to use standardized testing procedures to assess the students’ knowledge through different assessment categories. For example, students’ reading levels are assessed through their scores in vocabulary and comprehension; or students’ knowledge of mathematics is assessed through their scores in problem-solving and procedures. The educators are interested in estimating the amount of overlap in the information provided by two assessment categories and identifying a group showing the most (or least) amount of overlap. A procedure will be presented for selecting a population with the largest (or smallest) overlap coefficient under the assumption that scores in two categories follow a bivariate normal distribution. The proposed procedure will be described using data collected by one school system.
