Reading Venn Diagrams
Venn Diagrams
- Venn diagrams are used to visually show sets of data
- They are used when there are multiple options, and people can choose from either, both, or neither
- Each circle represents one possibility
Option A or Option B
- When reading a Venn diagram, it will be split up into the potential options, where each circle represents one.
- If a number is in that circle and is not in any intersecting sections, it means that it only belongs to that option
- In this case, 5 people only do A, and 6 people only do B
Intersections
- If a number is in an intersection, it means that they do both options
- In this case, 3 people do both A and B
Neither
- If a number is outside of any of the Venn circles, it means that they are not involved with either option
- In this case, 4 people do neither A or B
