What is the difference between a control group and an experimental group?

In an experiment, data from an experimental group is compared with data from a control group. These two groups should be identical in every respect except one: The difference between a control group and an experimental group is that the independent variable is changed for the experimental group, but is held constant in the control group.

What is a constant group in a science experiment?

It is a group that maintains a constant level of influence from different variables. The control group should attempt to replicate the natural phenomenon. Variables that are constant among the control and experiment groups are termed controlled variables.
