The correlation between intelligence test scores and grades is:

The correlation between intelligence test scores and grades is: (a) Positive

(b) Negative

(c) Perfect

(d) They are not correlated

✅ Correct option: (a) Positive

Explanation:

The correlation between intelligence test scores and academic grades is generally positive. This means that students who score higher on intelligence tests tend to achieve higher academic grades, while students with lower intelligence scores often achieve lower grades. However, this relationship is not perfect, because academic performance is influenced by many other factors such as motivation, teaching quality, study habits, emotional intelligence, and socio-economic background. Intelligence contributes significantly, but it is not the only determinant. Option (b) is incorrect because a negative correlation would mean higher intelligence leads to lower grades, which contradicts research findings. Option (c) is incorrect because the relationship is not perfect. Option (d) is also incorrect because numerous studies confirm a measurable positive relationship. Thus, the correct answer is positive correlation.
