Intelligence test scores are negatively correlated with family size.

Question

Quizplus · Accepted Answer

Studies have shown that there is a negative correlation between intelligence test scores and family size, meaning that, on average, as family size increases, intelligence scores tend to decrease. This phenomenon is often attributed to factors such as resource dilution, where parents have fewer resources (time, money, attention) to devote to each child in larger families.
