Expected Values for Continuous Random VariablesWe now define the expectation of a continuous random variable. In doing so we parallel the discussion of expected values for discrete random variables given in Chapter 6. Based on the probability densSteven M. Kay...
is not discrete the above summation does not make any sense. However, there is a workaround that allows us to extend the formula to random variables that are not discrete. The workaround entails approximating with discrete variables that can take on only finitely many values. Let , ,..., ...
Expected Values of Random Variables We already looked at finding the mean in the section on averages. Random variables also have means but their means are not
Expected value (also known as EV, expectation, average, or mean value) is a long-run average value of random variables. The expected value also indicates
For the example of rolling two dice and summing the results, there is an easier way to calculate the expected value. This random variable can be viewed as the sum of two random variables: the first die roll and the second die roll: ...
Finding & Interpreting the Expected Value of a Continuous Random Variable from Chapter 6/ Lesson 2 29K A continuous random variable deals with measurements with an infinite number of likely outcomes. Define random variables and learn how to compute and...
A continuous random variable deals with measurements with an infinite number of likely outcomes. Define random variables and learn how to compute and to interpret the expected value of a continuous random variable with the probability density function. ...
Expected Value and Variance of Discrete Random Variables An introduction to the concept of the expected value of a discrete random variable. I also look at the variance of a discrete random variable. The formulas are introduced, explained, and an example is worked through. Mean & Expected Valu...
