Experiments that test to see if dogs are color blind must use a control group. Otherwise, the results are inaccurate and not scientifically valid.
double blind technique
A double-blind study.
Double blind experiment.
A control group is the unaffected group in a science experiment.
a control group assures that an experiment will be repeatable
An unexposed subject is the "control" for the experiment. The purpose is to establish an idea of what would normally occur outside the testing procedure. Similarly, in human tests, an inactive "placebo" is given to some subjects to verify that the changes occur independently of the psychosomatic (belief-driven) effects. In a "double blind' experiment, the person distributing the medication also does not know whether any particular individual is receiving the actual drug or a placebo. This is hidden in coded form until the results are recorded.

The control group.
A double-blind experiment is one where both the participants and the researchers are unaware of who belongs to the experimental or control group until after the study is completed. This helps eliminate bias in the results by ensuring that neither the participants' nor researchers' expectations influence the outcome.
A test group is the group in an experiment to which the change is being applied and the control group is the same type of group in an experiment to which nothing is done to compare the changes in the test group to.
control group
the answer to that question is the control group has nothing to do with the independent variable because a control group is some thing in your experiment that has not changed through out your experiment. And a independent variable is some thing in your experiment that you change through your experiment(s)
