The Answer is (a) For this problem, because the data are distinct categories, we would construct a bar diagram. Vertical scale extends from zero to a value high enough to include the largest frequency of 9. On the horizontal scale, the width of each bar should be the same with a small space between the bars. Because this is a nominal scale, it does not matter in what order we arrange the bars.
(b) The graph would look exactly the same; the only difference is that the divisions on the vertical scale would represent percentages rather than numbers of cases. The change can be accomplished merely by relabeling the divisions on the vertical scale: an ƒ of 1 becomes a % ƒ of 4; an ƒ of 2 becomes a % ƒ of 8; and so forth.
