Statistical Process Control Charts for Measuring and Monitoring Temporal Consistency of Ratings
Omar, M. Hafidz
Journal of Educational Measurement, v47 n1 p18-35 Spr 2010
Methods of statistical process control were briefly investigated in the field of educational measurement as early as 1999. However, only the use of a cumulative sum chart was explored. In this article other methods of statistical quality control are introduced and explored. In particular, methods in the form of Shewhart mean and standard deviation charts are introduced as techniques for ensuring quality in a measurement process for rating performance items in operational assessments. Several strengths and weaknesses of the procedures are explored with illustrative real and simulated rating data. Further research directions are also suggested.
