Definitions:

Experimental Group

In research, a group of subjects who are exposed to the variable under investigation, allowing researchers to assess the effect of this variable.

Control Group

A group in an experiment or study that does not receive the experimental treatment and is used as a benchmark to measure how the other tested subjects do.

Confounding Variables

Factors other than the independent variable that may cause a result in an experiment, potentially leading to incorrect conclusions.

Descriptive Methods

Research techniques used to describe characteristics of a population or phenomenon, involving observations and surveys without influencing the subjects.
