1. Identifying and Graphing Variables

2. Identify….
If you spend more time studying, then your grade will improve.
Independent Variable =
Dependent Variable =

3. Now You Try:
If you spend more time studying, then your grade will improve.
Independent Variable = amount of time spent studying
Dependent Variable = grade

4. Now You Try:
If the temperature of the room is increased, then the bacteria will grow faster.
Independent Variable =
Dependent Variable =

5. Now You Try:
If the temperature of the room is increased, then the bacteria will grow faster.
Independent Variable = temperature of room
Dependent Variable = bacterial growth

6. Organize your data Put your data into a data table Independent
Variable
__________(unit)
Levels
Dependent Variable _______________ (unit)
Trial Trail Trail mean range

7. After all of the data from the experiment is collected, then its time to organize the data.

8. Independent Variable vs. Dependent Variable
Also Known As:
Manipulated Variable
Responding Variable
Results:
Cause
Effect
On a graph:
X axis
Y axis

9. Step 6: Organize your data
Make the data table into a graph
GRAPHS make it EASIER to see patterns in the data!

10. Step 6: Organize your data
How do you know what goes on each axis of the graph?

11. Step 6: Organize your data
DRY MIX
Dependent Variable = Responding Variable = Y axis
Manipulated Variable = Independent Variable = X axis

12. Parts of a graph
Y Axis
X Axis

13. Y Axis (Dependent Variable) X Axis (Independent Variable)
Parts of a graph
Y Axis (Dependent Variable)
X Axis (Independent Variable)

14. Graphing: DRY MIX
Dependent Variable
Independent Variable
