This Printable Venn Diagram was created around 1880 by John Venn to compare sets of elements. They are an excellent way to pique children's interest in logic, computer science, and statistics. John Venn was a philosopher and logician from the United Kingdom. In addition to inventing the now-ubiquitous compare and contrast chart, Venn made contributions to set theory, probability, and statistics. These fields were crucial in the development of today's sophisticated computers. The printable Venn Diagrams below compare only two items, but other Venn Diagrams can be created to compare multiple items.
