Hypergeometric Calculator

The hypergeometric calculator is a smart tool that allows you to calculate individual and cumulative hypergeometric probabilities.

Apart from it, this hypergeometric calculator helps to calculate a table of the probability mass function, upper or lower cumulative distribution function of the hypergeometric distribution, draws the chart, and also finds the mean, variance, and standard deviation of the hypergeometric distribution.

What is hypergeometric distribution?

Specifically, a hypergeometric distribution is said to be a probability distribution that simply represents the probabilities that are associated with the number of successes in a hypergeometric experiment. You can try this hypergeometric calculator to figure out hypergeometric distribution probabilities instantly.

Suppose that you randomly selected 5 cards from an ordinary deck of playing cards, here you might ask: what’s the probability distribution form the number of red cards in our selection.

In this example, selecting a red card would be referred to as a success. Well, the probabilities associated with each possible outcome are an example of a hypergeometric distribution, as shown in the given chart:

By given this probability distribution, you can depict at a glance that the cumulative and individual probabilities are being associated with any outcome. For instance, the cumulative probability of selecting 1 or fewer red cards would be 0.175, and when it comes to the individual probability, selecting exactly 1 red card would be 0.15.

Hypergeometric Distribution Formula:

The hypergeometric distribution probabilities or statistics can be derived from the given formula:

Formula:

h(k; N, n, K) = [ KCk ] [ N-KCn-k ] / [ NCn ]

Where;

N is said to be the Population Size

K is said to be the number of Successes in population

n is said to be the Sample Size

k is said to be the number of Successes in Sample

C is said to be combinations

h is said to be hypergeometric

FAQ's

How do you know when to use hypergeometric distribution?

You can use the hypergeometric distribution with populations that are so small, which the outcome of a trial has a large effect on the probability that the next outcome is a non-event or event. For instance, within a population of 10 people, only 7 people have A+ blood. So, try the above distribute calculator to find the hypergeometric distribution.

What is a hypergeometric experiment?

The hypergeometric experiment has two particularities that are mentioned-below:

• The random selections from the finite population take place without any replacement
• Each item in the population can either be considered as a success or failure

However, a hypergeometric distribution indicates the probability that associated with the occurrence of a specific number of successes in a hypergeometric experiment.

What is the number of successes?

When it comes to hypergeometric experiment, each item in the population can be represented as a success or a failure. The number of successess is said to be a count of the successes in a particular grouping. Therefore, the number of successes in the sample indicates a count of successes in the sample; and the number of successes in the population indicates a count of successes in the population.

What is a hypergeometric probability?

A hypergeometric probability is said to be a probability that is associated with a hypergeometric experiment.
