Question

Quizplus · Accepted Answer

A longitudinal study is designed to investigate a specific phenomenon by collecting data repeatedly over time. This type of research is useful for studying changes in behavior, attitudes, or outcomes over time, and can provide important insights into the long-term effects of various interventions or treatments. A case study is a more focused investigation of a single individual or group, and is not necessarily conducted over multiple time points. Pragmatic and cross-disciplinary studies are terms that are not directly related to the design of research investigations.
