Abstract
This chapter gives a brief overview of discrete and continuous random variables, their mean
and variance. Some discrete probability distributions are given, including binomial distribution, Poisson
distribution, hypergeometric distribution, computation of their probabilities and frequencies and simulation for these distributions are given on SPSS. Continuous probability distributions include only normal
distribution.
Keywords: Discrete and continuous random variables, Probability distribution, Probability density function, Binomial distribution, Poisson distribution, Hypergeometric distribution, Normal distribution.
