Question 2 Use the table of measurements of length and force that you have been supplied with to complete the following activities: (a) Draw a scatter graph for your given data. Describe what the scatter graph is indicating. Use the scatter graph to estimate the length for a force of 57N Calculate the line of regression of extension on force (Y on X) Calculate the regression coefficient (e) Explain what the regression coefficient indicates? (f) Use the equation for the line of regression to predict the length for a force of 57N (g) Compare the calculated value with the value that you have determined from the scatter graph. Refer to Page 18 to note down your values Force (N) Length (mm) (b) (c) (d)
