A. Continuous vs. Discrete Distributions. 1. Random Variable-rv – a variable whose value is a numerical outcome is a random phenomenon. One and only one numerical value is assigned to each outcome. The r.v. can be either discrete or continuous. a. Discrete random variable – a random variable that takes on whole numbers or integers. b.

To leave the discrete probability distribution, press 2nd QUIT. To find the mean (expected value) and standard deviation, press the STAT key, highlight CALC using the arrow keys and then select the 1-VAR STATS option (#1). Then enter L1, L2. Remember L1 is x and L2 is P(x). Press ENTER to view the descriptive statistics.

DISCRETE RANDOM VARIABLES. NOTE: In this class we will only consider discrete random variables with a strictly finite sample space. We will . not. consider discrete random variables with a countable sample space. Here are a couple of examples of discrete random variables, one of which has a finite S and the other has a countable S. 1.
