A study design that randomly assigns participants into an experimental group or a control group. As the study is conducted, the only expected difference between the control and experimental groups in a randomized controlled trial RCT is the outcome variable being studied. The variables being studied should be the only variables between the experimental group and the control group. To determine how a new type of short wave UVA-blocking sunscreen affects the general health of skin in comparison to a regular long wave UVA-blocking sunscreen, 40 trial participants were randomly separated into equal groups of an experimental group and a control group. All participants' skin health was then initially evaluated.

Introduction to study designs - case-control studies
Case–control study | Psychology Wiki | Fandom
Cohort and case-control study are two of the designs used in research between which some difference can be identified. A researcher who is about to conduct a study on a specific field usually has research objectives and questions. Based on these, the researcher chooses a research design that will be most appropriate for the study. A cohort study is a research design where the researcher studies a group of people, also known as a cohort, for a longer period of time.
A nested case—control NCC study is a variation of a case—control study in which cases and controls are drawn from the population in a fully enumerated cohort. Usually, the exposure of interest is only measured among the cases and the selected controls. Thus the nested case—control study is more efficient than the full cohort design.
A case study is an in-depth study of one person, group, or event. In a case study, nearly every aspect of the subject's life and history is analyzed to seek patterns and causes of behavior. Case studies can be used in a variety of fields including psychology, medicine, education, anthropology, political science, and social work. The hope is that learning gained from studying one case can be generalized to many others. While case studies focus on a single individual or group, they follow a format that is similar to other types of psychology writing.
