Definitions:

One-Group Pretest-Posttest Uninterpretable Design

Refers to a simplistic experimental design where a single group of subjects is tested before and after an intervention without a control group, making causal interpretations difficult.

Internal Validity

The extent to which a study can demonstrate a causal relationship between variables, free of confounding factors.

Random Assignment

is a process used in experimental designs to allocate participants to different groups in a study by chance, minimizing pre-existing differences among those groups.

Pretest-Posttest Nonequivalent Groups Design

A quasi-experimental design involving two groups that are not randomly assigned, with both groups measured both before (pretest) and after (posttest) a treatment or intervention.
