Principles of Measurement

This course is a tutorial in measurement theory and concepts and their application to problem solving and decision-making. The objective is to understand the information (evidence) that is generated by measurement procedures (tests, questionnaires, inventories, interviews and so on) and to be able to use that information to make decisions. Critical to this process is how valid and reliable is this information. 

We examine the cornerstones of measurement: reliability, validity, and test bias and fairness. Practical issues in test construction are considered for developing measures of typical and maximal performance. Most courses in psychometric theory, test theory or measurement theory have a heavy emphasis on explaining test theory. The present course places the emphasis on application of these concepts.
