Examples of the use of Multiple Linear Regression (MLR) techniques are presented. This is done to show how MLR aids data processing and decision-making by providing the decision-maker with freedom in phrasing questions and by accurately reflecting the data on hand. A brief overview of the rationale underlying MLR is given, some basic definitions are offered, and MLR is described as the process of defining alternative linear models and using appropriate test statistics to determine the model which best satisfies the criteria of simplicity and goodness of fit. Following this, an actual question of interest to an educational decision-maker is stated, and a linear model which reflects the relevant factors is presented. The process of "testing the question" is outlined. An action-oriented interpretation of the data analysis and the resulting steps to be taken by the administrator are described. (Author/PB)
