    • 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.
