Psychometrics (PSY501)

I no longer teach this course. However, if you are a student in this course, the following information may be useful.

Psychometrics is the study of the measurement of psychological attributes. This course will consist of a statistics "primer" section lasting approximately 6-8 weeks, after which we will focus on more complex multivariate procedures and the application of statistics to testing data.
