[Complete the statement with an appropriate conclusion or implication based on the given correlations.]

Answer :

Final answer:

The study shows a positive correlation between age and IQ scores in young children. As the age of the children increases, their IQ scores also tend to increase.

Explanation:

The study demonstrates that IQ scores of 4- and 5-year-olds, 6- and 7-year-olds, and 8- and 9-year-olds have positive correlations to varying degrees. Correlation coefficients are used to measure the strength and direction of the relationship between two variables. In this case, the correlation coefficients of 0.80, 0.87, and 0.90 indicate a strong positive relationship between age and IQ scores in these age groups. It suggests that as children get older, their IQ scores tend to increase.
