What is Hypergeometric Distribution?

If there are R Pepsi cans in a total of N cans (N-R Cokes) and we are asked to identify them correctly, in our choice selection of R Pepsi, we can get k = 0, 1, 2, … R Pepsi. The number of correct guesses and the probability of correctly selecting k Pepsi cans is Hypergeometric distribution.

Hypergeometric distribution is typically used in quality control analysis for estimating the probability of defective items out of a selected lot.

The Pepsi-Coke marketing analysis is another example application. Companies can analyze the preferences of one product to other among a subset of customers in their region.

Learn more about Hypergeometric distribution and how to derive the probability from the ground up in lesson 38 of our data analysis classroom.
