• Make sure it is accurate by repeating or using
large experimental groups.
• Needs to have a control, independent variable
and a dependent variable.
Experimental Group

experiment that all of the testing is
done on or to. This group will give
you the answer to the problem and
this group will prove your hypothesis
to be correct or incorrect.
