Day 2

Look at the Types of Graphs foldable

Bar Graph

Double Bar Graph

Bar graphs use bars of differentlengths to show andcompare numerical data.Double bar graphs use more than one bar to be able to compare more than one set of data on the same graph.

More examples of bar graphs

You will use the rest of the class to ask your classmates their preference (choice) for the survey that you have selected. Keep track of the responses using tally marks. For homework, you will then create a bar graph on the graph paper showing your results.

Choices:• Favorite ice cream (choose 3 flavors plus OTHER)• Favorite subject (math, science, language arts, soc. studies)

• Favorite color (choose from 3 colors plus OTHER)• Favorite soda (choose from 3 plus OTHER)• Favorite holiday (choose from Christmas,

Halloween, Thanksgiving, and OTHER)

Circle Graph

(Pie Chart)

Circle Graphs (pie charts) are used to compare parts of a group to the whole group. The whole circle is the whole group. 

More examples of circle graphs

Pictographs

also called picture graphs

Pictographs use pictures or symbols to represent data amounts.   

PictographsPay attention to the key when using pictographs because the picture or symbol may represent more than one like in the example below:

Line Graph

Line graphs are used to show how data changes over time.Double line graphs use more than one line to be able to compare more than one set of data.

Line Graph exampleExample 1: The table below shows daily temperatures for

New York City, recorded for 6 days, in degrees Fahrenheit.

Temperatures In NY City

Day Temperature

1 43° F

2 53° F

3 50° F

4 57° F

5 59° F

6 67° F

The data from the table above has been summarized in the line graph to the right.

Example 2: Sarah bought a new car in 2001 for $24,000. The dollar value of her car changed each year as shown in the table below.

Value of Sarah's Car

Year Value

2001 $24,000

2002 $22,500

2003 $19,700

2004 $17,500

2005 $14,500

2006 $10,000

2007 $ 5,800
