Graph regression line on scatter plot
WebA scatter graph is drawn using the following steps: Step 1: Decide on the two variables that you will be comparing. Step 2: Collect and tabulate data for these variables. The x / independent variable will be tabulated in the second row and your y / dependent variables will be in the third. Step 3: Use your collected data to plot the points. WebGraphically, this can be seen in the plot below. The distance from each point to the line is the error, depicted in the graph above as e 1, e 2, e 3, and e 4. The linear regression line returns the values of m (slope) and …
