In the following activities, you will perform linear, exponential and quadratic regressions. Analyze the fit of a regression line/curve using correlation coefficients and the coefficient of determination.



Tip

Use the graphing calculator to generate the curve of best fit and to calculate the correlation coefficient and the coefficient of determination. You can also use the calculation features of the graphing calculator to find the zeros of the regression equation. Refer to the Student Resources for specific calculator steps.
