What Is A Control In A Scientific Experiment
Camila Farah
You can have as many controls as necessary to achieve results.
The control can be an object population or any other variable which a scientist would like to control. This isolates the independent variable s effects on the experiment and can help rule out alternative explanations of the experimental results. The control must remain the same or equal at all times in order to receive accurate results. A control refers to the control group in a scientific experiment.
Controls are also helpful because they permit scientists to identify possible mistakes or errors in the experiment if. A control group in a scientific experiment is a group separated from the rest of the experiment where the independent variable being tested cannot influence the results. A control variable is any factor that is controlled or held constant in an experiment. Controlled experiment a controlled experiment is simply an experiment in which all factors are held constant except for one.
In other words it is a possible independent variable that the scientist has no interest in investigating. A single experiment may contain many control variables. For this reason it s also known as a controlled variable or a constant variable. This isolates the effect of the independent variable and helps eliminate alternative explanations of the investigation results.

A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. Without a control researchers would not have anything to compare the experiment s results to. This increases the reliability of the results often through a comparison between control measurements and the other measurements. All variables are identical between the two groups except for the factor being tested.
Scientific controls are a part of the scientific method. A control setup in a scientific experiment is separate from the main experiment and is a setup in which the independent variable under investigation cannot affect the results. A common type of controlled experiment compares a control group against an experimental group. By definition the control in a science experiment is a sample that remains the same throughout the experiment.
Controls are a vital part of a science experiment. An experimental control is used in scientific experiments to minimize the effect of variables which are not the interest of the study.
