Comparing the intelligence of boys and girls on the dimensions of family efficiency

Raven's Progressive Matrices IQ test is one of the valid intelligence tests that is used to measure general intelligence. This research was conducted to compare the general intelligence of male and female students on the dimensions of family efficiency and on the basis of children's Raven intelligence.

The research method was comparative causal and the statistical population was all primary school students in the city in the academic year 1399-1400. The sample of the study was 1643 elementary students (808 boys and 835 girls) who were selected by cluster random sampling from two areas and half. In this study, the children's Raven color matrix test and the non-verbal part of the Stanford Binet version 5 test were used to collect data. Research data were analyzed by independent t-test and multivariate analysis of variance.

The results showed that there was no significant difference between the intelligence of girls and boys in the first, second, third, fourth and sixth grades, but the difference in intelligence between girls and boys in the fifth grade was significant to the negation of boys. There was also a significant difference between the mean total score of intelligence of girls and boys in educational levels. In other words, there was a significant difference in the intelligence scores of students in different grades and with the increase in age, intelligence also increased.

By examining the background of the research, it was found that social factors, especially the family, can have a great impact on intellectual functions.
