Experimental Research

Experimental research is a methodological approach that systematically manipulates one variable to determine its effect on another variable, within a controlled environment.

Random Assignment

A method used in experiments to distribute participants across various control and experimental groups in a way that each participant has an equal chance of being assigned to any group, minimizing biases.

Preexisting Differences

Differences among study participants that exist before the application of an experimental manipulation.

Correlational Research

A type of non-experimental research method that examines the relationship between two variables without manipulating them.
