- Initial CRAN release.
- Implements classical test theory item analysis for multiple-choice
tests, including item difficulty (p-value), item discrimination
(point-biserial and upper-lower 27 percent index), distractor
analysis (per-option frequency, proportion, and point-biserial),
and Haladyna's distractor efficiency.
- Wrapper function
mcq_analysis() returns an S3 object with
print, plot (difficulty-discrimination scatter), and
apa_table methods.
- Includes a simulated example dataset
mcq_example of 200 students
on a 30-item four-option test.
- Verified by 78 unit tests using testthat.
