Question

Quizplus · Accepted Answer

A normal distribution is characterized by its symmetrical and bell-shaped curve, which means that the majority of the data falls near the mean, with fewer and fewer data points spread out toward the tails. There is no restriction on negative values, and the standard deviation can be any value. While the mean is an important characteristic of a normal distribution, it is not the only defining feature.
