Question

Quizplus · Accepted Answer

This is a quasi-experimental study because the researcher cannot randomly assign participants to smoking one pack or two packs a day. The variable of smoking is not being manipulated by the researcher, so it is not a true experimental study. It is not a correlational study because the researcher is interested in cause-and-effect relationships, rather than just examining associations between variables. Independent variables are a broad category of variables that could apply to many different types of studies, but do not specifically describe this study.
