Statistics expected value calculator
WebSep 20, 2024 · The expected value formula is this: E (x) = x1 * P (x1) + x2 * P (x2) + x3 * P (x3)… x is the outcome of the event P (x) is the probability of the event occurring You can have as many x z * P (x z) s in the equation as there are possible outcomes for the action you’re examining. There is a short form for the expected value formula, too. WebMay 4, 2024 · We will use the Friedman Test Calculator using the following input: Once we click “Calculate” then the following output will automatically appear: Step 3: Interpret the results. The test statistic is Q = 12.35 and the corresponding p-value is p = 0.00208. Since this value is less than 0.05, we can reject the null hypothesis that the mean ...
