Using Response Times in Answer Similarity Analysis

• In Event: Response Times

Abstract

We expand the definition of answer similarity to include not only the item scores/responses, but also the item response times. Using detailed simulations and an experimental data set, we show that the new statistics are much more powerful, on average, than existing statistics at detecting several types of simulated collusion.
