      Aug 27, 2013 · discrete random variable. Do #5,7 page 353 . When analyzing discrete random variables, we’ll follow the same strategy we used with quantitative data – describe the shape, center, and spread, and identify any outliers. The mean of any discrete random variable is an average of the possible outcomes, with each outcome weighted by its probability.

      mean, or . first moment) of a . random variable. is the . integral. of the random variable with respect to its . probability measure. For discrete random variables this is equivalent to the probability-weighted sum of the possible values. The term "expected value" can be misleading. It must not be confused with the "most probable value."
