Theoretical expected value
Webb24 nov. 2024 · First, let’s calculate the expected bonus per month. You do this by multiplying each possible value by its respective probability and add the products. Remember, the bonus probabilities were: $1000 with probability 0.6. $500 with probability 0.3. $0 with probability 0.1. Therefore, the expected value for 1 month is: WebbDivide by the Correct Value. Multiply by 100 to produce a percentage. When calculating this statistic, some fields of study retain the plus or minus values to indicate whether the Estimate is above or below the Correct value. However, other areas use the absolute value of the error, which always produces positive values.
