  1. INTER-RATER RELIABILITY WITH SAS - A Practical Guide for Nominal, Ordinal, and Interval Data (Review excerpts by clicking this). The primary goal of this book is to show practitioners simple step-by-step approaches for organizing rating data, creating SAS datasets, and using appropriate SAS procedures, or special SAS macro programs to compute various inter-rater reliability coefficients.
  2. HOW TO COMPUTE INTRACLASS CORRELATION USING EXCEL - A Practical Guide to Inter-Rater Reliability Assessment for Quantitative Data. (Review excerpts by clicking this)
    I wrote this to offer researchers and students, practical guidelines for computing various Intraclass Correlation Coefficients (ICC) using Microsoft Excel. I wanted these guidelines to be clear and sufficiently detailed for anybody with access to MS Excel to be able to organize research data, choose the correct ICC statistic, and perform the calculations with confidence.
  3. HANDBOOK OF INTER-RATER RELIABILITY (3rd Edition) - (Review excerpts by clicking this) -This handbook is for researchers, practitioners, instructors and students. It reviews the most widely-used inter-rater reliability coefficients, and proposes several alternatives. This authoritative work is the definitive guide to measuring the extent of agreement among raters for nominal, ordinal, and interval data.
