Detailed explanation-1: -gives us information about specific populations. Which would provide the strongest evidence that education influences IQ scores? When comparing groups of children of the same age who differ in number of years of education, children who have one extra year of education have higher IQs.
Detailed explanation-2: -Empirical evidence suggests that especially parental education, parental income, and maternal IQ are important predictors of intelligence. Parental education together with maternal IQ and the child’s sex were found to account for 24% of the variance in IQ at age 5 [6].
Detailed explanation-3: -Twin and Adoption Studies Some of the most convincing evidence for a genetic component to intellectual ability is provided by twin studies. Researchers have performed many studies comparing the IQ of fraternal twins and the IQ of identical twins.
Detailed explanation-4: -The correlation of intelligence test scores for identical twins raised together is about +. 85. For identical twins raised apart, the correlation is about +. 72.
