Significance of linear regression
WebTo explain the relationship between these variables, we need to make a scatter plot. To plot the above data in a scatter plot in Excel: Select the data. Go to the Insert Tab > Charts Group. Click on the scatterplot part icon. Choose a scatter plot type from the drop-down menu. Excel plots the data in a scatter plot.
