Source A practical application of Venn diagrams using set theory In the example below, both A and B are sets while their overlap, also known as the intersect, is referred to as A∩B. Where shapes or sets have overlapping regions indicate the elements or characteristics shared by those sets. Let’s explore Venn diagram symbols used in set theory in detail: Intersection (∩) The overlapping region or where sets overlap is known as the intersection of two. The most basic type of Venn diagram consists of two circles, and each represents a unique characteristic. These shapes can also be referred to as Venn diagram sets. I’m sure you’ve seen symmetric Venn diagrams where shapes of the same size are used. Set theory is just a fancy way of defining the process of understanding how different data relate to each other. To understand Venn diagram symbols, we need to understand set theory. Here’s an example: CREATE THIS DIAGRAM What are the symbols of a Venn diagram?įor most use cases, we can define a Venn diagram with three symbols: If you dig deeper, Venn diagrams can be better defined as visual aids that help demonstrate symbolic logic, which is a system of symbols to determine the validity or invalidity of arguments for deductive reasoning. On the surface, a Venn diagram shows similarities and differences between data sets.īut that would be doing John Venn, the British mathematician who designed these diagrams a disservice.
