Hypergeometric distribution, in statistics, distribution function in which selections are made from two groups without replacing members of the groups. is the population size. Let’s say you were drawing playing cards from a 52 card deck. The total population size is 52 (since there are 52 cards in the deck). Enter a value in each of the first four text boxes (the unshaded boxes). Online help is just a mouse click away. most. Given this probability distribution, you can tell at a glance the individual and cumulative probabilities associated with any outcome. The function can calculate the cumulative distribution or the probability density function. Statistics Glossary. However, it tends to be a binomial distribution when N is large. The hypergeometric distribution deals with successes and failures and is useful for statistical analysis with Excel.
