## The Definition and the Uses of Venn Diagram

**Venn Diagram Worksheet Key** – You’ve probably read about or encountered the **Venn diagram** in the past. Anyone who has attended Mathematics specifically Algebra and Probability, must have a good understanding of this image. It is a visual aid used to illustrate the relationship between a collection of objects. Learn more about this commonly used diagram in different areas and fields below.

## What Is a Venn Diagram?

A Venn diagram is an illustration of overlapping circles to demonstrate the relationship between objects or groups of items. In the event that two circles overlap, they share certain characteristics in common, while those that don’t overlap mean that they don’t share a commonality. Each circle is usually is accompanied by a brief description of what category it represents.

It’s used to illustrate similarities and differences in a visual way among different objects, groups or concepts. It is commonly found in the field of education as a valuable tool. It’s also been used across the globe from the beginning decades of the twentieth century at elementary levels as a vital part of the logic curriculum.

The diagram was popularised via John Venn, an English logician from the 1880s. Similar diagrams were developed in the early 1700s from Leonard Euler, a Swiss mathematician, who called them Eulerian circles. The term wasn’t used for a long time until Clarence Lewis, an academic philosopher and conceptual pragmatism founder employed it in 1918. At the time, it was used to refer to a circular illustration in his book, which was titled “A Survey of Symbolic Logic.”

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

The Venn diagram is utilized often in the academic world. Teachers in the school utilized the diagram in teaching math concepts such intersections, sets, and unions. In more advanced maths the tool is also used to solve complicated problems. It is also possible to find diagrams within the field of statistics, particularly predictive analytics.

Apart from mathematics-related disciplines it is also used to study similarities and differences between various languages. In the business world, it is used to compare products as well as services. It is also used to display any other information pertinent.

Here is the explanation of how the diagram will be able to do:

- Visually organize information to look for connections (similarities in addition to differences) between sets of items.
- Regardless of the complexity level, display the logic of particular concepts. They also serve as visual aids to show the connection between them.
- When deciding which goods or services to purchase take the time to compare different options and clearly see the similarities and differences between them.
- Solve many mathematical problems.
- Analyze data sets, uncover correlations, and then evaluate the probability of particular events.
- Reason logic that supports equations or statements, and the process of grouping.

One of the primary reasons for why one of the main reasons why Venn diagram can be so effective and so popular is because of its ease of use. It lets you examine things, find out the areas where they intersect and differ and also serve as a visual representation of the relationship. Along with pie charts, quadrant charts, bar graphs flow charts and many other tools for visualizing data, they provide an effective way to present your data or assist in the method of thinking.
