WARM UP 1.What is the difference between a bar graph and a histogram? 2.How do you find the class width? 3.A line graph represents what? 4.Make a stem and leaf plot of the following data points

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!
