Coefficients of Interrater Reliability and Agreement
R Package for modeling ICC variance components and obtaining individual or group-specific reliability estimates.
A R script that reads two sets of scores from a JSON file and calculates the intraclass correlation coefficient (ICC) to compare them. Results are saved in a text document. Designed for psychological research.
Conducted in Python, this analysis examines the internal consistency (using Kuder-Richardson Formula 20 [KR-20]), inter-rater reliability (using Intraclass Correlation Coefficient [ICC] and Cohen's Kappa), item difficulty and discrimination indices, and the relationship between multiple-choice and essay sections for mixed-format achievement tests.
