Ethnic and sex differences on the test of nonverbal intelligence, Quick Test of intelligence, and Wechsler...

This study investigated the performance of 89 students on the Test of Nonverbal Intelligence, Quick Test, and Wechsler Intelligence Scale for Children-Revised IQ scores for ethnic and sex differences. The sample consisted of 61 males, 28 females (37 Black, 52 White). A two-way analysis of variance and the new Duncan's Multiple Range Test were used to identify significant differences between the mean scores. The findings did not indicate any significant differences between the IQ scores with regard to ethnicity or sex. Implications of these findings are discussed in terms of assessing minority group members with the Wechsler Intelligence Scale-Revised, Test of Nonverbal Intelligence, and Quick Test.
