Make a Venn diagram. What is a Venn diagram? Venn diagram history Venn diagrams are named after British logician John Venn. Example Venn diagram Say our universe is pets, and we want to compare which type of pet our family might agree on.

Set A contains my preferences: dog, bird, hamster. Venn diagram purpose and benefits To visually organize information to see the relationship between sets of items, such as commonalities and differences. Students and professionals can use them to think through the logic behind a concept and to depict the relationships for visual communication. This purpose can range from elementary to highly advanced. To compare two or more choices and clearly see what they have in common versus what might distinguish them.

This might be done for selecting an important product or service to buy. To solve complex mathematical problems. To compare data sets, find correlations and predict probabilities of certain occurrences. Venn diagram use cases Math: Venn diagrams are commonly used in school to teach basic math concepts such as sets, unions and intersections.

Set theory is an entire branch of mathematics. Statistics and probability: Statistics experts use Venn diagrams to predict the likelihood of certain occurrences. This ties in with the field of predictive analytics. Different data sets can be compared to find degrees of commonality and differences.

Logic: Venn diagrams are used to determine the validity of particular arguments and conclusions. In deductive reasoning, if the premises are true and the argument form is correct, then the conclusion must be true.

For example, if all dogs are animals, and our pet Mojo is a dog, then Mojo has to be an animal. In argument form, we say: All C are A. Therefore B is A. A related diagram in logic is called a Truth Table, which places the variables into columns to determine what is logically valid.

It uses lines to define sets. Venn then further developed mathematician George Boole's theories in the work Symbolic Logic , in which he highlighted what would become known as Venn diagrams. These graphics were pictorial representations of the relationships between sets, with similar diagrams having been used by Gottfried Leibniz and Leonhard Euler.

Though quite complex in their orientation and application, Venn diagrams have become a trademark tool over the years in the teaching of introductory math and logic, as well as being used by popular media to illustrate relationships between groups and concepts.

Venn was elected to the Royal Society in and continued to publish other works, including The Principles of Empirical or Inductive Logic and volumes on the history of Cambridge and a list of its alumni, compiled with the aid of his son, John Archibald Venn.

The Euler diagram shows just the possibilities we have factual data for already. The Venn diagram shows the same information—the topics the three friends did individually, and the Math topic that Anwar and Lucy both chose.

However, we also have intersections that are void of data but represent all other possibilities. The orange intersection on the left represents the instance in which Jans, along with Anwar, remembers his Math homework as well as Science—but in this hypothetical outcome, Lucy forgets to complete work for Math. The green intersection on the right imagines the same fate for Anwar.

Ready to create your own Venn diagram? To produce a Venn diagram, there must be both commonalities and differences between the two data sets. If all the information categorized is identical, your diagram would look like this:. Even with two data sets, if the information contained has no differences, the two curves would overlap entirely, creating just one circle.

The opposite problem, two data sets with no commonalities, would also not create a Venn diagram but a perfectly acceptable Euler diagram showing disjoint sets. Surprisingly, something that looks as familiar as the example below is also not mathematically considered to be a Venn diagram.
