Key Concepts

Intervention

An intervention is a deliberate change or treatment introduced into a study to determine its effect on the dependent variable. It is a key component in experimental research, providing a basis for evaluating the efficacy or impact of specific behavioral or environmental modifications.

Control Group

This group does not receive the experimental treatment and serves as a baseline against which the effects of the intervention are compared. Including a control group helps to isolate the impact of the independent variable on the outcome by reducing potential confounding factors.

Dependent Variable

The dependent variable is the outcome that is measured after the manipulation of the independent variable. It is the variable that researchers monitor to see if it has been affected by the intervention, indicating the study’s effect.

Experimental Design

This concept refers to the overall framework of the study that involves comparing different groups under controlled conditions to establish cause-and-effect relationships. In such designs, participants are divided into groups, each receiving a different treatment or no treatment, and their outcomes are subsequently compared.

Independent Variable

In research, the independent variable is the condition or factor that is manipulated by the researcher to observe its effect on the outcome. In studies of this type, it is the intervention or treatment given to one group, intended to produce a measurable change in behavior or outcome.
