All of us have at some point in life have taken standardized tests like SATs, GMATs, GREs, and TOEFL. A test of progressive difficulty that aims to assess our verbal, quantitative, and pattern-seeking ability. We have all taken surveys, Likert scale items, multiple response questions, and MCQs but how do we know that it measures what it does? What does that actually measure?

That is where psychometrics comes in. It is the field of study that helps researchers develop and evaluate through complex mathematical modeling tools, the reliability, and validity of our instruments. With the power of machine learning and large datasets, it has become easier to quantify social phenomena like political opinions, educational trends, criminal behavior, and personality preferences.

On Tuesday, February 16th I will be talking to one of the leading psychometricians Dr. Okan Bulut. He is a professor of Educational Psychology at the University of Alberta and has worked at premier institutions developing assessments at Pearson, PluralSight, and the American Institute of Research. He is the author of the book ‘Handbook of educational measurement and psychometrics using R.’ You are in for a real treat!
