used for comparison
Control Group
Parts of the experiment that stay the same
(control variables, control factors, or constants.)
Control

THE DIFFERENCE
Independent Variable
Factor that occurs as a result of the change, the part of the experiment that is recorded
(responding variable)
*Results or measurements
