What is the formula for the standard deviation in a beta distribution?

  1. (P-O)/6

  2. (P-O)/4

  3. (ML-O)/2

  4. (P-ML)/3

The correct answer is: (P-O)/6

The formula for the standard deviation in a beta distribution is (P-O)/6. This formula is derived from the beta distribution formula, where P represents the pessimistic estimate, and O represents the optimistic estimate. Option B is incorrect because (P-O)/4 is not the correct formula for the standard deviation in a beta distribution. Option C is incorrect because (ML-O)/2 is not the correct formula for the standard deviation in a beta distribution. Option D is incorrect because (P-ML)/3 is not the correct formula for the standard deviation in a beta distribution. The correct formula, (P-O)/6, is used to calculate the standard deviation in a beta distribution, taking into account both the optimistic and pessimistic estimates.
