A controlled experiment is an exceptionally centered method for gathering information and is particularly helpful for deciding examples of circumstances and end results. This kind of experiment is utilized in a wide assortment of fields, including medicinal, mental, and sociological research.  

To direct a controlled experiment, two groups are required:  an experimental group and a control group.  

The experimental group is a gathering of people that are presented to the factor being analyzed. The control group, then again, isn't presented to the factor. It is basic that all other outer impacts are held consistent.

The main thing that is diverse between the two gatherings is the factor being inquired about.
