One of the calculation/SD question from Test 2 of mock exam.
Ideally per formula result should be 2 not 4
142. A Project Manager wants to determine the variance for an activity estimate using the three point estimate with the following data Pessimistic=14, Optimistic=2, Realistic=5. What is the variance ?
Answer (c) The formula for variance = [( Pessimistic-Optimistic)/6] squared. The answer is 4.
