I. Section 5.1: Introduction A. A Random Variable is a variable whose values correspond to the outcome of an experiment. B. A numerical random variable can be classified as being either discrete or continuous . 1. A discrete random variable is one that may assume either a finite number of values or an infinite sequence of values such as 0,1,2,… (arises from the counting process) 2. A continuous random variable is one that may assume any numerical value in an interval or collection of intervals. (arises from a measuring process)
