How to Use Kappa Analysis for Multi-Assessor Quality Control (Fleiss' kappa)

When you need to assess whether multiple quality assessors agree on product classifications, you need more than just a simple pass/fail system. In this video, I discuss a more advanced method called Kappa analysis, which can handle multiple assessors and more complex product classification systems, such as three or five categories. Kappa analysis helps determine how consistently assessors apply criteria to the same products. By comparing their classifications and calculating agreement levels, you can identify areas where measurement systems need improvement. This method can be applied to various classification systems, including nominal, ordinal, or even binary data, providing a deeper insight into your quality control processes. I walk you through the process of setting up and calculating Kappa analysis for multiple assessors, including how to interpret the results and what actions to take if the agreement scores are low. The Kappa value helps identify if you can trust your measurement systems, and if not, where to focus your improvement efforts. By the end of the video, you'll have a solid understanding of how to assess your measurement systems effectively. #ContinuousImprovement #QualityControl #MeasurementSystems    • How to Use Kappa Analysis for Multi-A...   Chapters: 0:00 Introduction to Multi-Assessor Kappa Analysis 2:20 How to Set Up Kappa Analysis for Multiple Categories 4:30 Sample Selection and Data Collection 6:50 Calculating Agreement Between Assessors 8:30 Understanding the Kappa Formula 11:00 Interpreting Kappa Scores 13:30 Practical Applications and Limitations 16:00 How to Use the Results to Improve Quality Control Interested in working with me to boost Operational Excellence in your organisation, or perhaps a more personal coaching on your CI career?
