See something odd.

Make an If…then… statement.

ExperimentExperiment
You must identify and control the variables.
If…I.V.…then…D.V.…◦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.

Control the VariablesControl the Variables
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.

ConclusionConclusion
Look at the data to see if your hypothesis was correct.
Write about it.Identify errors in controlling the variables.
