Section 2.5
There are FIVE ways we will look at that people try to mislead you with their graphs.
1) TRUNCATED GRAPHS
Ways to Mislead
Truncated• The vertical scales of graphs
are altered to distort information.
What is wrong with this graph?
Are they the same?• The graphs below show the number of people who rode
buses from September through February.
2) SCALING
Ways to Mislead
SCALING• The size of a graph or a
figure is altered to distort information.
TOO MUCH INFORMATION
3) HARD TO READ
What is wrong with this graph?
4) Misuse of data or percentages
5) Misuse of pictures
CREATE TWO GRAPHS
1) One regular graph
2) One misleading graph
3) Label both graphs clearly!
