Subject: Graphing and Linear Regressions

Topic:Graphing using real world NasCar race data

Purpose:To illustrate the concepts of data collection, linear regression, data interpretation.

Materials:

- Graphing Calculators
- Computers with Internet access
- Graph Paper

Description:In this activity the students will collect and graph speed, time and/or distane data on moving objects (race cars, rockets, airplanes, etc.)

Procedure:

- Search the Web to locate data on race cars, rockets, airplanes, or any type of moving vechicle.
- Interpret, explain and or describe data sets.
- Determine the best set of axis and plot data.
- Use Graphing calculator to determine Line of Regression Equation
- Graph Line of Regression on graph with data points

Assessment:Students will explain, both written and in a verbal presentation, their interpretation of the data. Students will use their equations, graphs and data to answer questions and make predictions and estimations onpossible outcome. Finally, students will compose a test to be given using their data.
