What do you know about graphing?
Why is graphing important to use when representing data?

2. How to set up successful graphs in Mrs. Morrison’s class!

3. How to set up your graph!

4. (This is for your dependent variable)
How to set up your graph!
Y Axis
(This is for your dependent variable)

5. How to set up your graph! X Axis
(This is for your independent variable)

6. NFL History - Touchdown Leaders
TAILS
NFL History - Touchdown Leaders
T - Title

7. TAILS T - Title A - Axis NFL History - Touchdown Leaders
Y Axis = Dependent Variable
NFL History - Touchdown Leaders
T - Title
A - Axis
X Axis = Independent Variable

8. Decide on an appropriate scale for each axis.
TAILS
NFL History - Touchdown Leaders
Decide on an appropriate scale for each axis.
Choose a scale that lets you make the graph as large as possible for your paper and data
T - Title
A – Axis
S – Scale

9. How to determine scale
Athlete
Number of Touchdowns
Jerry Rice
208
Emmitt Smith
175
LADAINIAN TOMLINSON
162
Terrell Owens
156
RANDY MOSS
154
Scale is determined by your highest & lowest number.
In this case your scale would be from

10. How to determine Intervals
Athlete
Number of Touchdowns
Jerry Rice
208
Emmitt Smith
175
LADAINIAN TOMLINSON
162
Terrell Owens
156
RANDY MOSS
154
The interval is decided by your scale.
In this case your scale would be from and you want the scale to fit the graph.
The best interval would be to go by 50’s.

11. TAILS T – Title A – Axis I – Interval S – Scale
The amount of space between one number and the next or one type of data and the next on the graph.
The interval is just as important as the scale
Choose an interval that lets you make the graph as large as possible for your paper and data
T – Title
A – Axis
I – Interval
S – Scale

12. TAILS T – Title A – Axis I – Interval S – Scale

LABEL your bars or data points
Jerry Rice
Emmitt Smith
L.T.
Terrell Owens
Randy Moss
Athlete
Label your Y Axis. What do those numbers mean?
Give the bars a general label. What do those words mean?

14. When to use… Bar graphs Used to show data that are not continuous.
Allows us to compare data like amounts or frequency or categories
Allow us to make generalizations about the data
Help us see differences in data
Line Graphs
For continuous data
useful for showing trends over time
