An experimental group is the group in an experiment that receives the variable being tested. One variable is tested at a time.

What is a control for an experiment?

A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables). This increases the reliability of the results, often through a comparison between control measurements and the other measurements.

What is experimental group in plant experiment?

Experimental groups are those being tested – the groups in which the independent variable is of special interest to the researcher. In your plant experiment, your experimental group might use a regular room light bulb as the light source.

What is an example of a control group and experimental group?
