**Elements of Statistical Methods Discrete & Continuous**

The random variable X can only take on the values 0, 1, or 2, so it is a discrete random variable. The probability distribution for this statistical experiment appears below. Number of heads... The values of a discrete random variable are countable, which means the values are obtained by counting. All random variables we discussed in previous examples are discrete random variables. We counted the number of red balls, the number of heads, or the number of female children to get the corresponding random variable values. The values of a continuous random variable are …

- Today: Discrete Random Variables Probability distribution function (pdf) for a discrete r.v. X is a table or rule that assigns probabilities to possible values of X.
- a mathematical description of a discrete random variable (RV), given either in the form of an equation (formula) or in the form of a table listing all the possible outcomes of an experiment and the probability associated with each outcome.
- Chapter 4 - Function of Random Variables Let X denote a random variable with known density fX(x) and distribution FX(x). Let y = g(x) denote a real-valued function of the real variable x. Consider the transformation Y = g(X). (4-1) This is a transformation of the random variable X into the random variable Y. Random variable X( ) is a mapping from the sample space into the real line. But so is
- Covariance for discrete random variables page 19 This concept is used for general random variables, but here the arithmetic for the discrete case is illustrated.
