Calculating the expected value is a fundamental concept in probability and statistics. It provides a measure of the average outcome of a random experiment over the long run. This article will guide you on using a calculator to find the expected value effortlessly.
Formula
The expected value (EV) is calculated by summing up all possible outcomes multiplied by their respective probabilities. In simpler terms, it’s the mean or average of a set of values.
How to Use
- Enter the values you want to calculate, separated by commas.
- Click the “Calculate” button.
- Instantly get the expected value result.
Example
Suppose you want to find the expected value of a set of numbers: 3, 6, 9. Enter these values separated by commas (e.g., “3, 6, 9”) and click “Calculate” to get the result.
