An Empirical Investigation of Multiple Matrix Sampling in an Elementary School Setting.
Novak, Carl D.
This study involving 352 students was designed to verify empirically the a priori use of multiple matrix sampling procedures in an elementary school using a nationally normed, commercizlly published achievement test. The study focused on effect of changes in item context, effect of previous exposure to items, and relative effectiveness of multiple matrix sampling procedures. Results indicated that multiple matrix sampling estimates of the mean were more accurate and estimates of the variance were as accurate as comparable examinee sampling estimates. Changes in item context affected matrix sample variance estimates. Previous exposure to items affected matrix sample mean estimates. (Author)
