Methods follow Lynn (1986) <doi:10.1097/00006199-198611000-00017>, Polit and Beck (2006) <doi:10.1002/nur.20147>, Aiken (1985) <doi:10.1177/0013164485451012>, and Lawshe (1975) <doi:10.1111/j.1744-6570.1975.tb01393.x>.https://github.com/r-universe/rafhq1403/actions/runs/28650647572Wed, 03 Jun 2026 21:03:59 GMTcontentValidity0.2.0successhttps://rafhq1403.r-universe.devhttps://github.com/rafhq1403/contentvaliditygetting-started.Rmdgetting-started.htmlGetting Started with contentValidity2026-05-05 19:32:542026-06-03 20:42:50rashed.alqahtani@gmail.com (Rashed Alqahtani)A unified toolkit for classical test theory (CTT) item analysis of multiple-choice test data, including item difficulty (p-value), item discrimination (point-biserial correlation and upper-lower 27-percent discrimination index), per-distractor analysis (frequency, proportion, and discrimination), and Haladyna's distractor efficiency. A wrapper function returns a tidy 'mcq_analysis' object with print, plot (difficulty-discrimination scatter), and APA-style table methods for direct inclusion in journal manuscripts. Implemented in pure R with no compiled code and minimal dependencies.https://github.com/r-universe/rafhq1403/actions/runs/27534241395Tue, 12 May 2026 07:21:32 GMTmcqAnalysis0.1.0successhttps://rafhq1403.r-universe.devhttps://github.com/rafhq1403/mcqanalysisgetting-started.Rmdgetting-started.htmlGetting started with mcqAnalysis2026-05-12 06:41:182026-05-12 07:19:58
