Detailed explanation-1: -Constant – the factor that remains fixed during an experiment while other variables change.
Detailed explanation-2: -Control groups are an important aspect of true experimental designs. The presence of control groups allows researchers to confirm that study results are due to the manipulation of independent variables (IVs) rather than extraneous variables.
Detailed explanation-3: -What is an Experimental Group? An experimental group consists of participants who are exposed to a particular manipulation of the independent variable. These are the participants who receive the treatment of interest.
Detailed explanation-4: -In an experiment testing the effects of a treatment, a comparison group refers to a group of units (e.g., persons, classrooms) that receive either no TREATMENT or an alternative treatment. The purpose of a comparison group is to serve as a source of COUNTERFACTUAL causal inference.
