Q:

What is a control setup in a scientific experiment?

A:

Quick Answer

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. This isolates the effect of the independent variable and helps eliminate alternative explanations of the investigation results.

Researchers use scientific methods to study the surrounding world to explain why the world is the way it is. They do this by conducting experiments, including controlled experiments, control setups and experimental setups. A controlled experiment is one in which only one variable is altered at a time in order to determine a cause and effect relationship. An experimental setup is conducted in the same manner as the control, but it includes one aspect to be measured. A control setup uses all the same equipment under the same conditions, but no variables are tested, and it provides a baseline with which to compare the results of the experiment setup.

A scientific experiment has several parts, including the independent variable, dependent variable, the control and the levels of independent variable. Other elements include repeated trials and constants. Control groups are further separated into two forms: positive and negative control groups. Positive control groups are groups in which the conditions of the experiment are put up to guarantee a positive outcome. A positive control group confirms that the experiment is working properly as desired, while negative control groups involve setting up conditions to cause a negative result.
