To display the distribution of grades (A,B,C,D,F) in a course, it would be correct to use (a) a circle graph?

but not a bar graph (b) a bar graph but not a circle graph (c) either a circle graph or a bar graph


I chose b, was I right?

I think you could use a bar graph or a pie chart. I'd go with (c).
Reply:It would not be incorrect to use either so (c). However, I think that a circle graph would be preferable as it would better show proportions of the total.
