A science experiment
a control is when someone is performing a science experiment, the control group is a test group that is kept neutral and is used as a standard of comparison, for example if you are doing an experiment on whether or not music affects concentration and you have 6 test groups, each listening to a different type of music, you would want one group to not listen to any music at all to compare to the other results.
