1. REPRESENTING DATA with GRAPHS
REFER TO YOUR REPRESENTING DATA HANDOUT AND GRAPHING WORKSHEET ON SPEED AND STOPPING DISTANCE TO STUDY FOR YOUR MIDTERM

2. GRAPH
A graph is a visual display of data and can help to reveal a pattern in data, if one exists. There are different types of graphs, including circle graphs, bar graphs, and line graphs

3. Circle Graphs Sometimes called a pie chart
The whole circle represents 100%
Which means data is recorded in percentages
All “pieces” must add up to 100%
Create a circle graph on your handout dividing your free time up into your hobbies or afterschool activities. Make sure the total is 100%
Add a title
Label each percentage
Label each “pie piece”

4. Bar Graph
Often used to show how a quantity varies with different factors
Create a bar graph using your quarter 1, quarter 2, and quarter 3 grade so far.
You should have 3 bars and give your graph a title
Label your Y axis and X axis appropriately
Make a 4th bar for the grade you would like to earn for 4th quarter

5. Line graphs
The points on the line graph represent the intersection of data for two variables
Sometimes the data is scattered and a line cannot be drawn through all points
Use a best fit line
Create a line graph of height and shoe size for the class
