All normal curves can be divided into areas in terms of the standard deviation.

Question

Quizplus · Accepted Answer

This statement is true. The standard deviation of a normal curve is a measure of its spread, and the area under the curve can be divided into sections based on how many standard deviations away from the mean a particular range of values falls. This is known as the empirical rule or the 68-95-99.7 rule, which states that approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.
