Enter your raw data values to calculate the expected value (mean). The calculator will automatically count frequencies, derive probabilities, and compute the expected value. This is useful when you have actual observations rather than known probabilities.
Enter numbers separated by commas, spaces, or line breaks
When you have raw observations (actual data points), the expected value is simply the arithmetic mean. The calculator counts how often each value appears, derives probabilities from frequencies, and computes E(X) = average of all values.
