   Oct 24, 2022 · expected value, in general, the value that is most likely the result of the next repeated trial of a statistical experiment. The probability of all possible outcomes is factored into the calculations for expected value in order to determine the expected outcome in a random trial of an experiment.

   How do you find the expected value of an experiment?

   • When the experiment involves numerical data, the expected value is found by calculating the weighted value from the data using the formula, in which E (x) represents the expected value, xi represents the event, and P (xi) represents the probability of the event.

   What is expected value of a random variable?

   • The expected value of a real-valued random variable gives the center of the distribution of the variable. This idea is much more powerful than might first appear. By finding expected values of various functions of a general random variable, we can measure many interesting features of its distribution.

   What is the expectation of a probability distribution?

   • If we calculate the mean of the outcomes it will be 4, the one which has a high frequency. It is clear now that the expectation is simply the Mean of the total outcomes. Hence, by looking at the probability distribution plot, one can find out what the expectation of that distribution is.

   Does expected value subsume probability?

   • If X is an indicator variable then E(X) = P(X = 1). In particular, if 1A is the indicator variable of an event A, then E(1A) = P(A), so in a sense, expected value subsumes probability. For a book that takes expected value, rather than probability, as the fundamental starting concept, see the book Probability via Expectation, by Peter Whittle.

   The expected value, or mean, of a discrete random variable predicts the long-term results of a statistical experiment that has been repeated many times. The standard deviation of a probability distribution is used to measure the variability of possible outcomes.
