Investigation of the Appropriateness of the Anchor Test Study Equating Results for Selected Subgroups. Final Report. Appendix C.
Bianchini, John C.; Vale, Carol A.
As part of an investigation of the appropriateness of the original Anchor Test Study equating results for black and Spanish-surnamed students, this Appendix lists the detailed results of the analyses for grade six, origanized by vocabulary, reading comprehension, and total reading scores. For each analysis, a two-page set of results is presented. The test-pair shown in the heading is so ordered as to indicate the direction of the equivalent score transformation; i.e., actual scores on the first member of the pair were transformed to equivalent scores on the second member. The first page indicates, for each of the ethnic groups, for each of the five score sub-ranges and for the total score range, the set of descriptive statistics, including the actual N, the weighted N, the mean discrepancy, and the standard deviation. The second page contains the summary of individual comparisons of blacks vs. whites and Spanish-surnamed vs. whites at each score level included in the two-way analysis. Those instances for which the entire Spanish-surnamed group was deleted are so indicated. The highest score level was deleted in about 75 percent of the two-way analyses, and the Spanish-surnamed group in about half. It was only occasionally necessary to delete the lowest score level. The post-hoc comparisons for the one-way analyses appear below those for each score level, under the heading "total score range." (RC)
