Probability Distributions
A probability distribution describes how the values of a random variable is
distributed. For example, the collection of all possible outcomes of a sequence of coin
tossing is known to follow the binomial distribution. Whereas the means of
sufficiently large samples of a data population are known to resemble the normal
distribution. Since the characteristics of these theoretical distributions are well
understood, they can be used to make statistical inferences on the entire data
population as a whole.
In the following tutorials, we demonstrate how to compute a few well-known probability distributions that occurs frequently in statistical study. We reference them quite often in other sections.
