Document Summary
Continuous random variable: a random variable that can take any numeric value. Discrete random variable: a random variable that can take one of a finite number4 of. Random variable: a random variable assumes any of several different numeric values as a result of some random event. Random variables are denoted by a capital letter such as x (p. 381). distinct outcomes is called a discrete random variable (p. 382). within a range of values is called a continuous random variable. The range may be infinite or bounded at either or both ends (pp. 382, 392). with each value of a discrete random variable x, denoted (x =x) or with any interval of values of a continuous random variable (p. 382). average value, the center of its model. Denoted or it is found (if the random variable is discrete) by summing the products of variable values and probabilities (p. 382):
