Now that you have represented your data graphically, it can be more easily analyzed.
⦁ Describe how the line of best fit and the correlation coefficient can be used to determine the correlation between the two variables on your graph.
⦁ Describe the type of correlation between the two variables on your graph. How do you know?
⦁ Does the correlation between the variables imply causation? Explain.
⦁ How do you calculate the residuals for a scatterplot?
⦁ Calculate the residuals for your scatterplot in step 2d.
⦁ Create a residual plot for your data.
⦁ Does your residual plot show that the linear model from the regression calculator is a good model? Explain your reasoning.
