STAT Intro Mathematical Statistics Introduction to STAT Section 6: If you were to roll a six-sided die an infinite amount of times, you see the average value equals 3. Definition and Calculating it was last modified: If the outcomes x i are not equally probable, then the simple average must be replaced with the weighted average, which takes into account the fact that some outcomes are more likely than the others. Search the site GO. Going back to the first example used above for expectation involving the dice game, we would calculate the standard deviation for this discrete distribution by first calculating the variance:. Given this information, the calculation is straightforward:. The expectation of X is. Although intuition is a good tool to guide us, it is not enough to form a mathematical argument and to prove that something is true. Back to Top Find an Expected Value in Excel Step 1: Chebyshev's inequality and the Berry—Esseen theorem. The expected value of this scenario is: This relationship can be used to translate properties of expected values into properties of probabilities, e. We present two techniques:.
