Descriptive Statement: Probability and statistics are the mathematics used to understand chance and to collect, organize, describe and analyze numerical data. From whether reports to sophisticated studies of genetics, from election results to product preference surveys, probability and statistical language and concepts are increasingly present in the media and in everyday conversations. Students need this mathematics to help them judge the correctness of an argument supported by seemingly persuasive data.

Resources INDY500  -students will find the mean and median speed for the Indianapolis 500. Rates per lap will be calculated as well as the                        length of each lap. Students will need to research information via the Internet. PopClock  -Students will review the Census Bureau's Homepage on the Internet and gather data regarding trends in population.                       They will study this data and make predictions on future populations and compare their results with the information                       available on the Internet. The Genetics Project  -During this project, students will complete surveys, formulate hypotheses, and use the data                                                  compiled by students around the globe to test their hypotheses. Olympic Statistics  -use years of data for a variety of classroom activities.
