People who like both pink and yellow

A Venn diagram is a series of interlocking circles that illustrate group membership by

placing an item in a circle group or overlapping region of two or more circle

groupings. Membership in the interlocking circles also denotes membership in the
larger circles.

For example, the image above is a Venn diagram illustrating color preferences. It
groups together those persons who like pink, those persons who like yellow, and

those persons who like both pink and yellow. The 15 people in the pink circle like

ONLY pink. In addition to those15 persons who ONLY like pink, seven people like pink
and yellow. The 16 people in the yellow group like ONLY yellow. In addition to the 16

people who like ONLY yellow, seven people like yellow and pink. This means that 22

TOTAL people like pink and 23 TOTAL people like yellow.

Venn diagrams are a good way to organize information that is not mutually exclusive

without losing the complexity of the various relationships. This could be useful in a
variety of ways. For example, if you give a survey that allows people to answer the

same question in more than one way, then a Venn diagram could help you interpret

the information and present it in a way that other people can understand. Consider
the following example.
