Discriminant Analysisof the Responses of a Sample of Students to the Stanford-Binet Intelligence Test, Fifth Edition

Abstract

research aims to determine the Discriminant ability of the Stanford-Binet Intelligence Test Fifth Edition to the responses of a sample of schoolchildren for the second and third grades(low achievement, average achievement, and high achievement),according to the achievement variable totaling 671 male and female students, including 329 males and 342 females.

The results indicated:

here are statistically significant differences between a sample of students with (low achievement, average achievement, high achievement) in all sub-tests, and that the higher averages were in favor of the group of outstanding students.

- There are statistically significant differences between a sample of students with (low achievement, average achievement, high achievement) in all sub-tests, and that the higher averages were in favor of the group of outstanding students.

 - Discrimination function between (low achievement, medium achievement, high achievement) in the Arabic language, the first discrimination function is the verbal visual processing test and the second is the liquid sub-test

- The accuracy of classification between groups was (32.4% for low achievement, 92.2% for medium achievement, and 52.3% for high achievement, with a rate of (77%), meaning that the accuracy of the classification can be reassured at a rate of (77%).

 - Discrimination function between (low achievement, medium achievement, and high achievement) in mathematics. The first discrimination function is the non-verbal working memory test, and the second is the verbal working memory test. - The classification accuracy between groups (34% for low achievement, 95.5% for medium achievement, and 6.35% for high achievement) with a rate of 83%, meaning that the accuracy of the classification can be assured at a rate of (83%).
