The subjects answered a set of assessment items seeking to determine their matrix reasoning abilities. Subjects that answered with a value between 0 to 7 were marked as incorrect. Subjects who answered a question with 10 selected the correct answer and, thus, were marked as correct.
From the OpenPsychometrics' code book that accompanied the data, they noted:
The possible answers were presented in two rows of four with a random order for each participant.
The collection of this data was of mediocre quality.
