How to fill out quadratic regression practice worksheet?
1. Start by plotting the given data points on a graph.
2. Draw a line of best fit through the data points.
3. Calculate the coefficient of determination (R^2) to measure the accuracy of the regression line.
4. Calculate the regression coefficients, b0 and b1, using the formulas for calculating the coefficients from linear regression.
5. Calculate the regression equation, y = b0 + b1x.
6. Calculate the predicted values of y for each given x value by substituting the x value into the regression equation.
7. Calculate the residuals for each given x value by subtracting the predicted y value from the actual y value.
8. Calculate the sum of squares for the regression and the sum of squares for the residuals.
9. Calculate the standard error of the estimate.
10. Calculate the coefficient of determination (R^2) to measure the accuracy of the regression line.
