Question

Quizplus · Accepted Answer

The center of a normal probability distribution is the mean of the distribution. This is where the highest point of the curve occurs, and therefore serves as the measure of central tendency for the distribution. The standard deviation is a measure of the spread or variability of the distribution, and may or may not be equal to the mean. The center of the distribution is not always equal to zero, and can be positive or negative depending on the mean and shape of the distribution.
