Classical Test Theory Item Analysis for Multiple-Choice Tests R package mcqAnalysis version 0.1.0 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. Software Depends: R (>= 3.5) Imports: stats, graphics, grDevices Suggests: knitr, rmarkdown, testthat (>= 3.0.0) Rashed Alqahtani <rashed.alqahtani@gmail.com> Comprehensive R Archive Network (CRAN) Rashed Alqahtani [aut, cre] (ORCID: <https://orcid.org/0000-0002-3317-204X>) MIT + file LICENSE (https://CRAN.R-project.org/package=mcqAnalysis/LICENSE) 2026-05-15 application/tgz https://CRAN.R-project.org/package=mcqAnalysis doi:10.32614/CRAN.package.mcqAnalysis
