1. Let’s GRAPH!
A 6 Step Solution

3. #1 Pick the appropriate graph.
Remember the tricks…
1 set of numbers = BAR GRAPH
2 sets of numbers = LINE GRAPH
Change over TIME = LINE GRAPH

4. #1 Pick the appropriate graph.5 54 10 45 15 29 20 25 18

5. # 2 Find the Independent Variable.
Known before the experiment begins; chosen by the experimenter.
DATA TABLE = 1st COLUMN
GRAPH = X-AXIS
Label (write) the VARIABLE & UNITS on the X-AXIS.

6. # 2 Find the Independent Variable.
Time
(min)
Temperature of Coffee (oC) X

7. # 3 Find the Dependent Variable.
DATA collected during the experiment; you have to “wait” for this one; what will you write down?
DATA TABLE = 2nd COLUMN
GRAPH = Y-AXIS
Label (write) the VARIABLE & UNITS on the Y-AXIS.

8. # 3 Find the Dependent Variable.
Time
(min)
Temperature of Coffee (oC) Y

9. #4 Write a TITLE for the graph.
Independent Variable vs. Dependent Variable
Remember to write out the complete IV and the complete DV.

10. #5 Determine the SCALE for the x & y.
Ask yourself, “What is the highest number for each axis?”
Count the number of LINES you have to work with.
DIVIDE:
HIGHEST number
Number of LINES
Each line should be “worth” this number

11. #5 Determine the SCALE for the x & y.
Time
(min)
Temperature of Coffee (oC) 5 54 10 45 15 29 20 25 18
Highest for the y axis
Highest for the x axis

12. #6 Add the DATA to the graph.
BAR GRAPH – Bars should be straight, not touching.
LINE GRAPH – Connect the DATA POINTS ONLY; do not connect the line to the origin, unless the origin is part of your data set.
