Mediating and Moderating Roles of Family Variables in the Relationship Between Children's IQ Scores and Parents' Educational Levels

This study explores the type and degree of interaction (mediating or moderating variables) in the relationship between children's IQ scores and their parents' educational levels. Specifically, it examines static variables such as differences in the educational levels of mothers and fathers, parents' occupations, parents' occupational compatibility, and the number of siblings. The research data will consist of the IQ scores of approximately 1,700 children whose intelligence was assessed at a university research center on gifted education, along with the corresponding family information. The data will be collected from the intelligence assessment application forms available at the center. Multiple linear regression analysis with mediating and moderating variable analyses will be employed to analyze the data. It is anticipated that the findings of this research will contribute new insights to the century-long nature-versus-nurture debate, the existing body of knowledge on intelligence, and to the understanding of gifted children’s families.
