When plаying gоlf, in mоst cаses the plаyer will want tо get the ball as close as possible to the hole when hitting a shot approaching the green. Suppose that two players hit 10 approach shots to a green, and their results are as shown in the two figures. The black dot is the hole, and the white dots are where each shot ended up. Description: The images above show the 10-shot from Pat and Ron. The left image is from Pat's 10 shots. The 10 white dots are more spread out in the picture. The right image is from Ron's 10 shots. The 10 white dots seem clustered together. How would you describe the measures of variation for each of the players?
