• Independent variable - Cause
• Dependent variable - Effect
• You need two groups to compare results.
• Control Group – does not get the I.V.
• Experimental Group – gets the I.V.
• Collect some data.
Experiment

The only thing different between the control group and the experimental group should be the independent variable.

• Use a large sample to get better results.
Control the Variables

Look at the data to see if your hypothesis was correct.

• Identify errors in controlling the variables.
