The calculation of the standard deviation for the beta distribution is based on the assumption that __________.
A)the range is divided by a count of the values used to compute the mean
B)the range is approximately equal to six times the standard deviation
C)the standard deviation is 50 percent of the mean
D)the standard deviation is the square of the statistical variance

Question

Quizplus · Accepted Answer

The standard deviation for the beta distribution can be calculated using the formula:
SD = (b-a) / (6 * sqrt(n)),
where b is the upper bound of the distribution, a is the lower bound, n is the sample size, and sqrt represents the square root. This formula assumes that the range (b-a) is approximately equal to six times the standard deviation.
