B)they have more internal validity than experiments
C)quasi-experiments randomly assign participants to groups.
D)all of these.

Question

Quizplus · Accepted Answer

Agency constraints often make true experiments infeasible, which leads researchers to use quasi-experimental designs instead. Quasi-experimental designs have less control over extraneous variables and weaker internal validity than experimental designs, but they still allow researchers to observe causal relationships without randomly assigning participants to groups. Therefore, B and C are incorrect, and D is not the best choice because it includes the incorrect option of B.
