Editing Probability distribution (section)

=== Discrete probability distributions ===
*'''Discrete probability distribution''': for many random variables with finitely or countably infinitely many values.
*''[[Probability mass function]]'' (''pmf''): function that gives the probability that a discrete random variable is equal to some value.
*''[[Frequency distribution]]'': a table that displays the frequency of various outcomes {{em|in a sample}}.
*''[[Relative frequency]] distribution'': a [[frequency distribution]] where each value has been divided (normalized) by a number of outcomes in a [[Sample (statistics)|sample]] (i.e. sample size).
*''[[Categorical distribution]]'': for discrete random variables with a finite set of values.
