Normal distributions differ from frequency distributions in that ______.

A) normal distributions are based on data you have actually collected
B) frequency distributions are based on an infinite number of scores
C) normal distributions are based on mathematical formulas
D) frequency distributions are theoretical distributions

Frequency Distributions

A statistical tool that organizes data by recording the number of times each value or group of values occurs.

Normal Distributions

A bell-shaped distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Mathematical Formulas

Equations used to describe relationships among different variables.
