A Movement-Matrix Technique for Determining Strata of Pre- and Post Change of Individual Subjects.
Poulos, Nicholis; Lindsey, John
Conventional methods used for the presentation of pre- and post statistical information generally are deficient in economy and compactness and fail to show internal movement from pre- to posttest. This technique precludes these shortcomings through the presentation of information in a highly visible manner which reveals the strata of internal change. It is closely related to the contingency-table approach but adds the missing bit of information -- what happened to the individual subject's scores between the pretest and posttest. Furthermore, the procedure will accept only individuals for whom there are both pre- and post measures. The method may be employed with cognitive or non-cognitive data and is equally adaptable to parametric or non-parametric measures. (Author/DLG)
