deviation IQ
A statistic obtained by dividing a person’s test score by the average test score of people in the same age group and then multiplying the quotient by 100 (see ratio IQ)
two-factor theory of intelligence
Spearman’s theory suggesting that every task requires a combination of a general ability (which he called g) and skills that are specific to the task (which he called s).
