Pengaruh panjang tes dan ukuran sampel terhadap kekerasan estimasi parameter pada teori respon butir (Item Response Theory)
Abstract: Developing fair and
objective test had been developed in many ways, but hey would solve huge educational
problem. Simulation study conducted by Hableton and Cook, inspired ths study to
looked for evidence the effect of test length and sample size on robustness of
item parameters estimation. This article gave more evidences in describing the
effect of tst length and sample size on robustness of item parameters
estimationin norm reference evaluation of item response theory.
Hypothecical data used in this study was generated by DGEN applicatioan
program. Test length was modeled in 15 and 55 items that represent short and
long test form. The sample size effect was tested by three different sample
sizee, 271, 605, and 1.999 to estimate 1,2,and 3 parameter according to the
rule of thumb.
