Definitions:

Nonequivalent Control Group Design

A quasi-experimental design where the experimental group and the control group are not created by random assignment, potentially leading to differences between groups that are not due to the experimental manipulation.

Selection Differences

Differences that arise in experimental research from the methods used to select participants for groups, potentially biasing the results.

Random Assignment

A method used in experiments to evenly distribute participants across various groups by chance, minimizing biases and ensuring groups are comparable.

Two Groups

Refers specifically to an experimental design wherein participants are divided into two distinct groups, often an experimental group and a control group.
