A normal distribution has a total of 6 standard deviations.

Question

Quizplus · Accepted Answer

In a normal distribution, approximately 99.7% of the data falls within 3 standard deviations from the mean (68% within 1 standard deviation, 95% within 2 standard deviations). Therefore, if we assume a normal distribution, the total number of standard deviations would be:

Mean - 3 standard deviations to the left + 3 standard deviations to the right = 6 standard deviations total

Therefore, statement A is true.

A Normal Distribution Has a Total of 6 Standard Deviations
