How to Use the Method of Adjusted Averages.
Keech, Catharine
The method of adjusted averages is presented in this paper as an easily applied statistical procedure useful in comparing average scores of two or three groups after an instructional period. Step-by-step preparations for using the method are described, including gathering scores from pre- and postinstruction measures of ability, dividing scores into strata, charting the strata, figuring averages, and using scores from an imaginary population to predict mean scores. Instructions for calculating the adjusted averages of the ninth grade classes of two sample schools are presented in detail, along with information on how to interpret the results. Other applications of the procedure that would be useful to teachers and evaluators are suggested. (AEA)
