Data and R Code for a Multi-Group Measurement Invariance Study of a National Grade-5 Numeracy Assessment, Grouped by School Location Type

Analytic dataset (domain-level numeracy scores, school identifiers, region) and R analysis code for a multi-group confirmatory factor analysis measurement invariance study, comparing schools by administrative location type in a national primary-grade assessment. Includes code for invariance testing, partial-invariance diagnosis, clustering-robust checks, balanced resampling, and a Monte Carlo false-rejection-rate simulation.
