What makes line graphs different from bar charts?

  • Line graphs are prettier
  • Line graphs show change over time; bar charts compare categories
  • Bar charts are always better
  • There is no difference
2

What does a steeply rising line on a graph mean?

  • The data is wrong
  • The value is increasing quickly
  • The value is decreasing
  • Nothing — lines do not mean anything
3

When should you NOT use a pie chart?

  • When you have categories
  • When you have too many categories or want to show change over time
  • When the data involves food

Why is accuracy more important than speed in reading graphs?

  • Speed does not matter at all
  • Because misreading data leads to wrong conclusions and bad decisions
  • Because teachers grade accuracy
  • Speed and accuracy are equally important
