I'm about 95% sure these instructions for Venn diagrams are unclear/ wrong: "The first three values specify the relative sizes of three circles: A, B, and C."
I'm working with a data set in which "A only" and "B only" are very small -- each is about 1% of cases, while "C only" is about 73% of cases. The remaining 25% of cases are various combinations: AB, AC, BC, ABC. To me, the instructions suggest that the first value should be the sum of "A only"+AB+AC+ABC, and so on for the second and third values. However, using those values yields a Venn where "A only" and "B only" are clearly larger than 1%. I tried using "A only", "B only" and "C only" as the first three values instead, and that produces a chart that -- on visual inspection -- seems to reflect the data better. However, I'm thinking that it's still not quite right -- the "C only" section looks larger proportionally than it should be, in comparison to the AB, AC, ABC sections of the chart. Can anyone tell me what I'm doing wrong?
