Measurement invariance is crucial for making valid comparisons across different groups (Kline, 2016; Vandenberg, 2002).

Parcels have been shown to alleviate skewness,…

A beta-binomial model is used to attribute standard errors to each estimate and to compare differences between the two types of libraries. (Author/LRW)
