Today you'll discover

  • what a bar graph shows best
  • what stacked bars show best
  • what a table shows best

Think firstThe same data, three displays

Which display best shows how each room splits into parts?

Decide first, then press Next. Ask what question each display answers fastest.

Three panels for how Room 12 and Room 14 get to school: a bar graph of Room 12's counts, 100% stacked bars for both rooms, and a table of shares. Each later frame rings one panel and writes its question underneath. The last step shows the same three displays for Grade 5's yard vote.
