1. From a set of student-generated points, students will create a list in the graphing calculator. Students will create a scatterplot of these points on the graphing calculator. Students will determine the linear regression equation and correlation coefficient for their data using the graphing calculator.

Materials List: graph paper, pencil, the Internet, spaghetti (uncooked to represent lines), graphing calculators, a math textbook. In this activity, students are exposed to scatter plots. Students will determine whether there is a positive, a negative, or no correlation in a data set and then find a line of best fit for a set of data.

(See the Unit 5 Graphing Calculator Directions handout for ways to find y given x.) With or without using the worksheet as a recording device, have the students write the regression equation, compare the regression equation they found on the calculator with the trend line they found by hand, discuss the advantages and disadvantages of doing the ...

graphing calculator - to find b0 and b1. You enter the X and Y values into your program or calculator, and the tool solves for each parameter. In the unlikely event that you find yourself on a desert island without a computer or a graphing calculator, you can solve for b0 and b1 "by hand". Here are the equations.

The Xres tells the calculator to use every pixel on the screen if Xres=1. The calculator will use one-fifth of the pixels if Xres=5, and so on. Leave the Xres at 1 unless you are graphing a very complicated, time-consuming function. Press GRAPH. An automatic window setting can be used instead of setting the window manually.
