OpenPsychometrics Data sets compiled from OpenPsychometrics’ raw data portal. These data sets have been processed to meet definitions for use in psychometric applications. Most notably, any observations with missing data have been removed and responses have been converted to a correct/incorrect marking for the items matrix. Matrix reasoning was used in Chen et al. (2020).
