Selection the best Method of Equating Using Anchor-Test Design in Item Response Theory
Explaining the problem. The equating process is used to compare the scores of the two different tests with the same theme. The goal of this research is finding the best method of equating data using Logistic model. Method. we are using the data of Ph.D. test in Statistic major for two consecutive years 92 and 93.

متن کاملFirst-order and Second-order Equity in Equating
iii Brennan Equity The notion of equity in equating was introduced by Lord (1980. pp. 195ff). The basic idea is that for any true score on Form Y, the distribution of observed scores on Form Y should be the same as the distribution of converted scores on Form X (see Kolen & Brennan, 2004. pp. 10–11). If this goal is achieved, Lord argued, then it should be a matter of indifference to each and e...
متن کاملIRT Observed-Score Kernel Equating with the R Package kequate
The R package kequate enables observed-score equating using the kernel method of test equating. We present the recent developments of kequate, which provide additional support for item-response theory observed score equating using 2-PL and 3-PL models in the equivalent groups design and non-equivalent groups with anchor test design using chain equating. The implementation also allows for local ...

متن کاملA comparison of Van der Linden's conditional equipercentile equating method with other equating methods under the random groups design
To ensure test security and fairness, alternative forms of the same test are administered in practice. However, alternative forms of the same test generally do not have the same test difficulty level, even though alternative test forms are designed to be as parallel as possible. Equating adjusts for differences in difficulties among forms of the test. Six traditional equating methods are consid...
