Why might researchers choose to use quasi-experimental designs over true experiments? Provide an example of such a case.
What will be an ideal response?
Ans: Varies.
Quasi-experimental designs do not permit the inference of cause and effect but they are often the only types of designs that are appropriate for investigating some research questions. From an ethical and practical standpoint, people cannot be randomly assigned to experience specific levels of certain independent variables (e.g., the experience of child abuse; gender). Researchers depend on quasi-experimental designs to investigate questions that feature subject variables and natural treatments. If a researcher is examining incidents of depression in soldiers who have or have not served in Iraq, they would be best served by using a quasi-experimental design (student examples will vary).
