The degree to which a quasi-experiment supports a causal claim depends on which of the following:

C) Its importance and its external validity
D) Its statistical significance and its practical significance
E) All of the above

Question

Quizplus · Accepted Answer

The design of a quasi-experiment (e.g. whether it has a control group, random assignment, etc.) and the results it produces (e.g. whether there is a significant difference between groups) are the most important factors in determining the degree to which it supports a causal claim. Choice B is not directly relevant to the validity of a quasi-experiment, while choice C and D relate more to the importance and practical relevance of the findings than to their causality. While all of the choices may have some bearing on the validity of a quasi-experiment, A is the best answer as it directly addresses the experimental design and outcome.
