Statistics expected value calculator
WebCalculator Use Variance is a measure of dispersion of data points from the mean. Low variance indicates that data points are generally similar and do not vary widely from the mean. High variance indicates that data values have greater variability and are more widely dispersed from the mean. WebThe table helps you calculate the expected value or long-term average.
