A Rasch unit, often referred to as a "logit," is a measurement unit used in the Rasch model, a statistical technique for analyzing categorical data, particularly in the field of psychometrics. It allows for the estimation of an individual's ability or trait level on a continuum based on their responses to items, while also taking into account the difficulty of those items. Rasch units facilitate comparisons across different tests and populations, providing a way to place individuals and items on the same scale. The logit scale is logarithmic, meaning that equal differences in logits correspond to equal differences in the underlying trait being measured.
