Definitions:

Quasi-Experimental Designs

Study frameworks that aim to identify causal relationships but do not incorporate random allocation to intervention and comparison groups.

Nonrandomly Formed Groups

Groups in a study that are created based on criteria other than random assignment, which can introduce biases or preexisting differences between groups.

One-Group Posttest-Only Design

An experimental design where a single group is exposed to an intervention and then tested, lacking a control group for comparison.

Uninterpretable Nonequivalent Groups Designs

Research designs that lack clear control groups or equivalency between groups, making findings difficult to interpret accurately.
