# AP Statistics

What do genetics, weather forecasting, emergency preparedness, political campaigns, and medical studies all have in common? The answer is statistics. Statistics is the mathematical science of gathering, grouping, and interpreting numerical data. And in this day and age, there’s a lot of data to make sense of. We’re going to help you get the statistical know-how to turn an intimidating Everest-sized mountain of numerical data points into a simple answer. Students are required to have access to a graphing scientific calculator.

**RECOMMENDED PREREQUISITE**: Algebra I required. Algebra II is recommended. Concurrent enrollment in Algebra II is acceptable.

Basic and On Demand are always open for registration.

Plus courses are created upon request.
