The known groups technique is used to establish a measure's convergent validity. Convergent validity is the extent to which a measure correlates with other measures of the same construct. The known groups technique involves comparing the scores of two or more groups that are known to differ on the construct being measured. If the measure has convergent validity, then the scores of the two groups will be significantly different.
