Rochester Interaction Record (RIR)

“In IRT-LR analysis, the null hypothesis of no group differences in trace lines is tested using information obtained in three steps. For instance, for the comparison of the performance of an item in a “focal” group (F) and a “reference” group (R), consider the hypothesis that b R…”

“A third contrasting feature of IRT relative to classical measurement methods is closely related to the first two. IRT approaches make extensive use of graphical depictions as a way of representing the properties of individual items and scales as a whole. We will look at some of…”

“This satisfies challenge (2) . The rest of this chapter describes the theoretical underpinnings of IRT as it is typically implemented within an adaptive test. We provide some brief overviews of the assumptions that underlie IRT and comment on the validity of IRT-based inferences…”
