WebTo find equivalent test scores between test forms X and Y with IRT observed-score equating, the recursion formula described in Lord and Wingersky is typically used although other alternatives exist (González et al. 2016).Let θ j the ability of examinee j, let x be a test score, and f r (x θ j) is the distribution of number-correct scores over the first r items for … Webpopulation sensitivity of the IRT equating functions computed for the MC section only and for the MC and FR sections together. We also compare the degree of population sensitivity across three equating methods: the IRT true score equating method and two observed score equating methods, chained equipercentile and Tucker linear equating.
