What is a control group, a indpendent variable and a dependent variable?
Answered by Ms. Sue
A control group is the group in an experiment that doesn't have anything change. For instance, if scientists are testing a headache medicine, the control group gets a placebo while the test group receives the product that they're testing.

Check these definitions for independent and dependent variables.
