Instructions are found in the Linear Project module and examples. this project have different phases. The phase 1 is to post your Linear Model Topic and your Data (SEE EXAMPLE FROM STUDENT ATTACHED IN

To complete the Linear Model portion of the project, you will need to use technology (or hand-drawing) to create a scatterplot, find the regression line, plot the regression line, and find r and r2.

Below are some options, together with some videos. Each video is limited to 5 minutes or less. It takes a bit of time for the video to initially download. When playing the video, if you want to slow it down to read the text, hit the pause icon. (If you run the mouse over the bottom of the video screen, the video controls will appear.) You may need to adjust the volume.

The basic options are to:

    (1) Generate by hand and scan. 

    (2) Use a free online tool 

  Use the free Desmos calculator: See DesmosLinearRegressionGuide.pdf to view how to generate a scatterplot and carry out linear regression.

The result of the free tool might not be as nice looking as the Microsoft Excel version, but it is free, accurate and easy to use.

    (3) Use Microsoft Excel.

 Visit Scatterplot - Start (VIDEO) to see how to create a scatter plot using Microsoft Excel and format the axes.

Visit Scatterplot - Regression Line (VIDEO) to see how to add labels and title to the scatterplot, how to generate and graph the line of best fit (regression) and obtain the value of r2 in Microsoft Excel.

    (4) Use Open Office.

    (5) Use a hand-held graphing calculator (See section 2.5 in your textbook for help with Texas Instruments hand-held calculators.)

The Linear Project Example uses Microsoft Excel.
