A Range-Null Hypothesis Approach for Testing DIF under the Rasch Model
A Range-Null Hypothesis Approach for Testing DIF under the Rasch Model is a scholarly work, published in 2009 in ''International Journal of Testing''. The main subjects of the publication include Null model, Rasch model, power of a test, sample size determination, Null distribution, range, econometrics, alternative hypothesis, measurement invariance, null hypothesis, type I and type II errors, NULL, sample, item response theory, Differential item functioning, test statistic, statistic, secure communication, clinical trial, one- and two-tailed tests, statistical test, mathematics, and statistics. The proposed statistic controlled the Type I error rates over all conditions and demonstrated acceptable power for sample size conditions of 5000 and larger.
