Organizing data using Venn diagrams

Topic Notes

In this lesson, we will learn:

  • How to describe common characteristics/attributes in groups of objects
  • What the regions of the Venn Diagram mean in order to sort objects by their attributes
  • The vocabulary "AND", "OR", and "NOT" within the context of Venn Diagrams

Notes:

  • Venn Diagrams organize data by sorting by characteristics ("attributes")
    • Circles are used to group objects by these characteristics
      • Objects inside the circle have the attribute
      • Objects outside the circle do NOT have the attribute
    • Objects with more than 1 attribute go into the overlapping part of attribute circles they belong to
    • A large rectangle surrounds all circles and objects, it represents all the objects

  • Alphabet letters are given to objects to save space when sorting in the Venn diagram

  • The vocabulary words "AND", "OR", and "NOT" have special meanings for sorting:
    • AND = means must have both attributes
    • OR = means having either attribute
    • NOT = means not including
