What is an example of a controlled group and a treatment group?

Which group receives the treatment or independent variable in a study?

They also closely resemble the participants who are in the experimental group or the individuals who receive the treatment.
What is a control group example?
A simple example of a control group can be seen in an experiment in which the researcher tests whether or not a new fertilizer has an effect on plant growth.

What is a treatment group in statistics?
Treatment groups are the sets of participants in a research study that are exposed to some manipulation or intentional change in the independent variable of interest. They are an integral part of experimental research design that helps to measure effects as well as establish causality.
When conducting an experiment the control group receives the treatment and the experimental group does not?
