Hyper- geometric distribution

Drawing without replacement from a population that is composed of two subgroups generates a hypergeometric distribution.

A hypergeometric distribution is defined by three parameters:

-the size of the population N

-the size of the subgroup D

-the size of the sample n.

P(X=k) is the probability that there are k successes (coming from the subgroup D) in the sample.

The probability distribution of the random variable X can be seen in the form of a bar chart or in the form of a table.

In the table you see the cumulative probability P(X<=k) and the probability P(X>=k).

By clicking in a cell of the table you see the corresponding part in red.

There are three options available.

Cumulative

The bar chart is drawn cumulatively. The color connection between table and graph is not active now.

Normal approximation

The normal or cumulative normal distribution, whichever fits best, is drawn.

Boxplot

A boxplot is shown under the bar chart.
