Studying Some Variables’ Interaction Effect on the Differences in Intelligence Scores Using the Snijders-Oomen Test

Abstract

The current research aimed to study the effect of the interaction of parental educational level, gender, and age on differences in intelligence scores using the Snijders-Oomen test. The research sample consisted of (900) male and female middle school students aged (13-14-15) years. The results showed the following:

- There is an interaction effect between age and the father's educational level on test responses. There are differences among students in intelligence based on the age variable, in favor of those with higher age. There are also statistically significant differences in test responses based on the father's educational level, in favor of those with higher educational levels.

- There is an interaction effect between age and the mother's educational level on test responses. There are differences in test responses based on the mother's educational level, in favor of those with higher educational levels.

- There is no interaction effect between age and parental kinship on test responses. There are differences among students in intelligence based on the parental kinship variable, in favor of those with no kinship. There is no interaction effect between age and gender on test response, and there are differences between students in intelligence according to the gender variable in favor of females
