Question

Quizplus · Accepted Answer

A bell-shaped pattern is a classic graphic representation of a normal distribution, which is common for many natural phenomena including intelligence test scores. This distribution allows for the calculation of measures like the mean and standard deviation, which can inform interpretations of individual scores and group differences. While intelligence quotient (A) and general intelligence (D) are related concepts, they do not specifically describe the distribution pattern of scores. The Flynn effect (C) refers to a trend of increasing intelligence scores over time and is not directly related to the shape of the distribution.
