The expected value (EV) is an anticipated value for an investment at some point in the future. In statistics and probability analysis, the expected value is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values.
How do you find the expected value of a data set?
To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products.
How do you calculate expected value in Excel?
To calculate expected value, you want to sum up the products of the X’s (Column A) times their probabilities (Column B). Start in cell C4 and type =B4*A4. Then drag that cell down to cell C9 and do the auto fill; this gives us each of the individual expected values, as shown below.
How do you calculate expected payout?
If you expect to win about $2.20 on average if you play a game repeatedly and it costs only $2 to play, then the expected payoff is $0.20 per game. In general, to find the expected value for a game or other scenario, find the sum of all possible outcomes, each multiplied by the probability of its occurrence.
How do you find expected value and standard deviation?
For each value x, multiply the square of its deviation by its probability. (Each deviation has the format x – μ). The mean, μ, of a discrete probability function is the expected value. The standard deviation, Σ, of the PDF is the square root of the variance.
Which is the formula for the expected value?
However, in finance, many problems related to the expected value involve multiple events. In such a scenario, the EV is the probability-weighted average of all possible events. Therefore, the general formula to find the EV for multiple events is:
How can I find out how much my home is worth?
In general, you can expect your home’s assessed value to amount to about 80% to 90% of its market value. You can check your local assessor or municipality’s website, or call the tax office for a more exact figure for your home. You can also search by state, county, and ZIP code on publicrecords.netronline.com.

Is there a way to calculate expected goals?
Some in-depth models include whether it was a goal scored with their feet or with their head, the situation that led to the shot and so on. This requires advanced data gathering and statistical analysis skills but it is still possible to gain insight using a far simpler expected goals system.
