Clearing the memory: Utilize the shortcut 2nd +) to clear any previously stored data or settings in the calculator.
Entering the data:
- Access the statistics menu by pressing stat.
- Choose the edit option to input your data set into the calculator.
Turning on stat plot:

- Ensure that Plot 1 is set to "on" for graphing.
Viewing the scatter plot:
- Use the zoom feature to adjust the viewing window.
- Select zoomstat to automatically fit the scatter plot to the data points.
Finding the least squares regression line (LSRL) equation and correlation coefficient:
- Navigate to the stat menu, then select calc.
- Choose linreg followed by the option to calculate to obtain both the LSRL and the correlation coefficient.
Creating a list of residual values:
- Access the stat menu and select edit.
- Scroll to L3 and find the list option (2nd stat), then select RESID to generate residuals.
Creating a residual plot:
- Return to the stat plot settings using 2nd y=.
- Set Plot 1 and scroll down to the Ylist option.
- Input L3 (2nd 3) for the residuals and use the zoom feature followed by zoomstat to visualize the residual plot effectively.
