Ethnic Group's Representation in Test Construction Sample and Test Bias.
Fan, Xitao; And Others
The hypothesis that faulty classical psychometric and sampling procedures in test construction could generate systematic bias against ethnic groups with smaller representation in the test construction sample was studied empirically. Two test construction models were developed: one with differential representation of ethnic groups (White, African American, Hispanic, and Asian) in each sample, and the other with exclusive representation of one ethnic group in each sample. Impact of group representation on the test item selection process and on ethnic groups' performance on the test forms developed was examined systematically using both parametric and nonparametric statistical techniques. Empirical findings based on the Texas Assessment of Academic Skills results over 190,000 11th graders consistently revealed that, for the tests constructed under the two models, there was no systematic bias against the group(s) with smaller representation in the test construction sample. Findings lead to the conclusion that the theory of genetic-environmental interaction, the theoretical underpinning of the hypothesis, may not be applicable in accounting for the dynamics of human testing. Seven tables present the data. (Contains 17 references.) (Author/SLD)
