Uniform Distribution

AAA

DEFINITION of 'Uniform Distribution'

In statistics, a type of probability distribution in which all outcomes are equally likely. A deck of cards has a uniform distribution because the likelihood of drawing a heart, club, diamond or spade is equally likely. A coin also has a uniform distribution because the probability of getting either heads or tails in a coin toss is the same.
