# Statistics

Data, data, everywhere you go! Information has gone from scarce to superabundant thanks to the powers of the internet and computing. But all this data means nothing without the ability to transform it in into something useful. Enter statistics. Everyone from crime analysts to journalists, Fortune 500 CEOs to insurance agents rely on statistics to analyze the information they need to make the best decisions. This class will give you the methods and know-how you need to discern probabilities, understand variables, and accurately measure and display data. In-depth labs and activities will help you soak up the entire statistical process including design, analysis, and conclusions. RECOMMENDED PREREQUISITE: Successful completion of Algebra II.
