What is the control group in psychology?

They also closely resemble the participants who are in the experimental group or the individuals who receive the treatment.

How do you identify a control group?

A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable’s effects on the experiment and can help rule out alternative explanations of the experimental results.

What is control condition example?

What is the control in an experiment?
