Organizing data using Carroll diagrams

Topic Notes

In this lesson, we will learn:

  • What the regions of the Carroll Diagram mean in order to sort objects by their attributes
  • The similarities and differences between the Carroll Diagram and Venn Diagram
  • How to describe pairs of opposite attributes

Notes:

  • Carroll Diagrams organize data in a table combining yes-or-no attributes
    • i.e. attribute #1 (yes) and NOT attribute #1 (no)
Carroll Diagrams

  • Sorting Data with Carroll Diagrams is similar to Venn Diagrams
    • Venn diagrams use circles to group what belongs or does not belong
    • Carroll diagrams use the column (vertical) and row (horizontal) of boxes

  • Some examples for pairs of opposite yes-or-no attributes:
    • "even number" and "not even number" (odd)
    • "odd number" and "not odd number" (even"
    • "less than 10" and "not less than 10" (10 or more)
    • "more than 5" and "not more than 5" (5 or less)
