1

What is a truncated y-axis?

  • An axis that goes to infinity
  • An axis that starts above zero, exaggerating differences
  • A broken axis
  • An axis without numbers
2

What is cherry-picking in data?

  • Choosing the best graph type
  • Showing only data that supports your argument while hiding the rest
  • Picking fresh data
  • Using real cherries in pictographs
3

How do 3D effects mislead in graphs?

  • They make graphs more accurate
  • Perspective distortion makes front items look larger and back items smaller
  • They add useful depth
  • 3D effects never mislead
4

What question should you always ask about any graph?

  • Is it colorful?
  • What data is NOT being shown?
  • Who made it look pretty?
  • Is it on the internet?
5

Why might someone start a graph at 95 instead of 0?

  • To save paper
  • To make a small difference between 97 and 99 look dramatic
  • Because 0 is too far away
  • There is no reason
6

What is the best defense against misleading graphs?

  • Avoiding all graphs
  • Checking axes, scales, labels, and asking what is missing
  • Only trusting graphs from friends
  • Never looking at data
7

Is it ever okay to not start the y-axis at zero?

  • Never
  • Yes, if clearly labeled and the zoom serves understanding, not deception
  • Always
  • Only for pie charts
8

What makes a graph 'honest'?

  • Bright colors and 3D effects
  • Full scale, consistent widths, all relevant data, clear labels, and appropriate type
  • Being made by a scientist
  • Having lots of data points
