The standard of comparison for checking or verifying the results of an experiment
(the “Normal” condition)

4. Experimental Design Terminology
Independent Variable:
The variable that is manipulated or changed by the scientist
* If I am the scientist, then I control this!
(graphed on x-axis)
Example: Length of Spaghetti Noodle

5. Experimental Design Terminology
Dependent Variable:
The measured result of changing the independent variable
(graphed on y-axis)
Example: Mass of Spaghetti Noodle

6. Experimental Design Terminology
Constants (Controlled Variables)
Conditions that are kept consistent throughout the experiment
What were the constants in the spaghetti noodle activity?
