Match the linear correlation coefficient to the scatter diag

Match the linear correlation coefficient to the scatter diagram. The scales on the x- and y-axis are the same for each scatter diagram. (a)r = 0.810, (b)r = 0.523, (c)r = 1 (a) Scatter diagram (b) Scatter diagram (c) Scatter diagram

Solution

c) r = 1 ans: I (because we can see that the response and explanatory are in perfect agreement)

a) r =0.81 ans: III (we can see that the response and explanatory are in good agreement)

b) r= 0.523 ans: II (we can see that the response and explanatory are not in good agreement infact it is the least)
