The Control Sets the Standard. By definition the control in a science experiment is a sample that remains the same throughout the experiment. The control must remain the same or equal at all times in order to receive accurate results.
A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
A control is a duplicate setup of the experiment you are performing with everything identical except for the variable that you are testing.
in my science class i did an experiment and you can only have one control just like you can only have one tested variable. controlled variable is the sample that stays the same in everybody's experiment. the variable is what is in the experiment. the tested variable is what you test or what you have different from everybody else.
What Does a Control Mean in Scientific Terms? In scientific terms, the word control means to create a group that experiences the same conditions as a test group during a study, without being exposed to the experimental factor or treatment that the test group is.

Control theory in control systems engineering is a subfield of mathematics that deals with the control of continuously operating dynamical systems in engineered processes and machines. The objective is to develop a control model for controlling such systems using a control action in an optimum manner without delay or overshoot and ensuring control stability.
Negative control groups are particularly common in science fair experiments, to teach students how to identify the independent variable.A simple example of a control group can be seen in an experiment in which the researcher tests whether or not a new fertilizer has an effect on plant growth.
Control group: Control group, the standard to which comparisons are made in an experiment. Many experiments are designed to include a control group and one or more experimental groups; in fact, some scholars reserve the term ‘experiment’ for study designs that include a control group.
