## The Definition and the Uses of Venn Diagram

**Venn Diagram Definition** – You’ve probably seen or read about a **Venn diagram** prior to. Anyone who has studied Mathematics particularly Algebra and Probability, must already be familiar with this diagram. Visual aid that illustrates the relation between two items. Find out more about this widely used diagram in different areas and fields below.

## What Is a Venn Diagram?

Venn diagrams are Venn diagram is an illustration of circles that overlap to show the interrelationships between different items or groups of items. Overlapping circles mean that they share a certain characteristic and those that don’t overlap, means they don’t have commonality. Each circle is usually is accompanied by a brief description of what category it represents.

It is used to represent the differences and similarities visually between groups, things or concepts. It is often used in the field of education as a valuable tool. It’s also been used around the world since the midst in the early 20th century, at the elementary level and as a crucial part of the logic curriculum.

The diagram was popularised via John Venn, an English logician in the 1880s. Similar diagrams were invented in the early 1700s by Leonard Euler, a Swiss mathematician. He referred to them as Eulerian circles. This being said, the term was not popular until Clarence Lewis, an academic philosopher and conceptualist who founded pragmatism employed it in 1918. In 1918, the term was used to refer to a circular illustration in the book he wrote, titled “A Survey of Symbolic Logic.”

## What Is the Purpose and Benefits of the Venn Diagram?

The Venn diagram is used a lot across the globe of academia. Teachers at the school use the tool in teaching math concepts, such as sets, intersections, and unions. At higher mathematics, it is also employed to tackle difficult problems. You can also find diagrams related to statistics, especially predictive analytics.

Outside of mathematics-related disciplines, it is also used to study similarities and differences between different languages. In the business world it is utilized to display comparisons of products, services, and anything applicable.

Here’s the outline of the diagram’s capabilities: can do:

- Visually organize information to search for relationships (similarities in addition to differences) between sets of items.
- – No matter the level of complexity, display the logic of specific concepts and serve visual representation to demonstrate the connections between them.
- If you’re deciding on what goods or services to purchase, compare several options and notice the similarities and distinctions between them.
- Solve various mathematical problems.
- Analyze data sets to identify correlations, and evaluate the probabilities of events.
- Reason logic that supports equations or statements, and groups.

One of the main reasons why Venn diagrams are so effective and popular Venn diagram can be so powerful and so popular is because of its ease of use. This tool lets you analyze things and determine the areas where they intersect and differ and serves as a visual representation of the relation. Alongside pie charts, quadrant charts, bar graphs flow charts and many other tools for data visualization offer a great method of presenting your data and aid the method of thinking.
