a bit from book to book. First are experimental designs with an in tervention, control group, and randomization of participants into groups. Next are quasi-experimental designs with an in tervention but no randomization.Descriptive designs d o not have an intervention or treatment and are considered nonexperimental.

Experimental research design is centrally concerned with constructing research that is high in causal (internal) validity. Randomized experimental designs provide the highest levels of causal validity. Quasi‐experimental designs have a number of potential threats to their causal validity.
