How to fill out 07 - quadratic regression

To fill out 07 - quadratic regression, follow these steps:

1. First, gather your data points that you want to analyze using quadratic regression. These data points should consist of pairs of independent and dependent variables.
2. Once you have your data, input it into a spreadsheet or a mathematical software program that supports quadratic regression analysis. This could be Excel, Python, or any other statistical software.
3. Open the quadratic regression tool or function within the software program. In Excel, for example, this can be found under the "Data Analysis" tab.
4. In the quadratic regression dialog box, you will be asked to provide the input range for your data points. Select the appropriate columns or cells that contain your independent and dependent variables.
5. Choose the output range where you want the regression results to be displayed. This could be a new sheet or a specific range within the current sheet.
6. Specify any additional options or settings for the quadratic regression analysis. This might include choosing the level of significance, enabling residuals calculation, or selecting the desired regression equation format.
7. Click on the "OK" or "Run" button to execute the quadratic regression analysis. The software program will then perform the calculations and generate the relevant regression outputs.
