2. Bar or Line?
One of the first things one needs to do when graphing is decide whether to make a bar graph or a line graph.

3. Bar Graphs are used for comparing
This bar graph compares the unemployment rates for people with different levels of education.

4. Line graphs are used for showing trends
This graph shows that the trend is that sales are increasing each year.

5. Line graphs also show relationships
This graph shows the relationship between elevation and temperature.
The higher the elevation, the lower the temperature.

6. Remember
TAILS
DRY
MIX
In order to make good graphs, all you have to remember is TIALS, DRY, and MIX

7. TAILS
T is for Title

8. Point out the title
People forget titles about 1/2 the time

9. TAILS
A is for Axis
We’ll talk more about the axis later

10. The Y axis goes up and down
The X axis goes side to side

11. TAILS
I is for Interval

12. Interval means make sure that each line is always worth the same amount…
Like here they went by 5’s

13. TAILS
L is for Label
People forget to label their axis about 1/3 of the time

15. S is for Scale TAILS Make your graph big enough to be easily read.
Use the whole paper or space instead of putting a tiny graph over in one corner

17. Remember that A was for Axis???
When figuring out what goes on which axis remember:
DRY
MIX

18. DRY DRY means that the: D ependent or
R esponding variable belongs on the
Y -axis

19. The percent depends on the quarter so the percent is the dependent or responding variable and belongs on the Y axis

20. MIX MIX means that the: M anipulated or
I ndependent variable belongs on the
X -axis

21. The Quarter is what we’re changing or manipulating so it is the independent variable and belongs on the X axis
