Understand Scientific Experimentation Terms

Variable in a controlled experiment that is deliberately

changed; the manipulated variable.

• Constant Variable

• Dependent Variable

• Control Variable

• Independent Variable

The variable that is observed/measured; the response variable.

• Independent Variable

• Control Variable

• Dependent Variable

• Hypothesis
