Introduction to Matrix Sampling for the Practitioner.
Sirotnik, Kenneth A.
One solution to the problem of obtaining test scores in order to assess multiple outcomes of educational programs is a basically simple technique called matrix sampling. Matrix sampling is the estimation of total test score statistics by administering random subsets of test items to randomly selected students. This chapter lays out the specific fundamentals of the matrix sampling procedure, including the needed terminology, notations, and types of sampling designs. This discussion is followed by sections on potential uses and limitations of matrix sampling methodology, specific computational procedures associated with the estimation of selected population parameters, and statistical as well as practical guidelines in the development of useful matrix sampling designs. Throughout these discussions, real-life examples are used to illustrate the concepts and procedures involved. A technical appendix is included, but the body of the text has been kept at a level commensurate with a one-semester course in elementary descriptive and inferential statistics. The statistical procedures employed focus on a rather simple and specific (but widely employed) matrix sampling design; however, the concepts generalize quite readily to more complex operations. (RC)
