Question

Quizplus · Accepted Answer

Experiments generally have the highest internal validity because they involve randomly assigning participants to different conditions and manipulating the independent variable, which establishes a cause-and-effect relationship between the independent and dependent variables. Quasi-experiments may lack some degree of control or randomization, correlational studies do not establish causality, and qualitative studies are often more exploratory and descriptive in nature.
