Here is a complete solution that shows you how to find the equation for the best curve fitting, how to draw that equation on the same screen as the scatter plot and also how to do interpolation or the best fit …... Then, students will determine the line of best fit. Although some exploration will be done with technology, students will also be asked to find the line of best fit by hand.

**TI-83/TI-83 Plus Procedure 22 Finding Best-Fit Models**

Name Class TI-82/83 Finding Best-Fit Models Example Enter the data from the table at the right. Find the line of best fit. STEP 1: Press to enter the years into how to get a job as a lounge singer Look back at your data (page 1.1). Under the Line of Best Fit you will see a value labeled r and r 2. These values, called the Correlation Coefficients, tell how well the Line of Best Fit actually fits the data. Think of these values as “percents of accuracy”. Ex: r=.98 is

**TI-83/TI-83 Plus Procedure 22 Finding Best-Fit Models**

Find the line of best fit (aka the least squares regression line) and the correlation are found together. Plotting the Points and Graphing the Line of Best Fit 1. Press STAT. 2. Press the right arrow key to Calc. 3. Select LinReg (#4) and press enter 4. Type 2nd 1 (L1), then comma, 2nd 2 (L2), then comma 5. The Press VARS Using the right arrow, move over to Y-vars, then press enter 1. Press how to find out credit on vodafone Graphing Scatter Plots and Mathematical Models on the TI-83. Two linear models are available on the TI-83: a. The median-median line (Med-Med) is given in the form y=ax+b, where a is the slope of the line, and b is the y-intercept. b. The least squares linear regression line. As a linear model, this minimizes the sum of the squares of the difference between each point’s actual y-value
