In this activity, students categorize various data sets using Carroll and Venn diagrams to sort, compare, and classify objects.

The Venn and Carroll diagrams may be over a hundred years old, but it's still highly used in today's modern lessons from science, math, and computing to arts and design. Its utility has gone beyond teaching logical thinking.

• A Carroll diagram is a logic diagram used for grouping things in a yes/no fashion. Numbers or objects are either categorized as 'x' (having an attribute x) or 'not x' (not having that attribute).
• A Venn diagram is a diagram that shows all possible logical relations between a finite collection of different sets.
