Assessment of perceived functional capacity: Using Rasch analysis to evaluate the measurement properties of four perceived pain & disability scales.

"Pick Me, Pick Me, I Want to Be a Counsellor": Assessment of a MEd-Counselling Application Selection Process using Rasch Analysis and Generalizability Theory.

“…The reason why inferences cannot be made from ordinal data is because raw scores include unwanted parameters (Wright, 1997). Through Rasch analysis these raw scores are calibrated so that the logit scores create a distribution of person abilities and item difficulties that can be compared and measured (Lochhead, 2009). (Linacre, 2010) Andrich (1996) explained that the scaled responses are similar to dichotomous measurement; however, the only difference is that the rating scale model partitions responses into intervals across the latent unidimensional linear construct.…”

“…With a partial credit model, the person would be able to get 4/5, suggesting that he or she was close to getting the final answer correct. In this version of the rating scale, each individual item has the freedom to vary in its number of estimates (Lochhead, 2009). The Rasch-Masters partial credit model for person ability and item difficulty is shown below:…”

Math play's effects on mathematics attitude and awareness: A Rasch Analysis

“…Rasch analysis is an approach to evaluate the instruments. Rasch analysis promises sample free estimates of item difficulty and person ability estimates free of the effects of the sample of items used to measure the person's characteristics (Bond & Fox, 2012;Linacre, 2012a,b,c,d, n.d.;Lochhead, 2009;Sebok, 2010).…”
