Question

Quizplus · Accepted Answer

The research approach, whether it is experimental, quasi-experimental, or non-experimental, plays a significant role in the internal validity and evidence for causation of a research study. Experimental designs are considered the gold standard for establishing cause-and-effect relationships, while quasi-experimental designs can provide some evidence for causation. Non-experimental designs are limited in their ability to establish causation because they lack control of extraneous variables. Therefore, the research approach used can impact the internal validity and evidence for causation of a study.
