Verified step by step guidance

1. Understand the key characteristics of each research design option provided: Cross-sectional, Longitudinal, Case study, and Experimental designs.
2. Recognize that a Cross-sectional design involves collecting data at a single point in time from different participants to compare groups.
3. Know that a Longitudinal design involves collecting data from the same participants repeatedly over multiple occasions or periods of time to observe changes.
4. Identify that a Case study design focuses on an in-depth analysis of a single individual or group, usually without repeated measures over time.
5. Recall that an Experimental design manipulates variables to determine cause-and-effect relationships, which may or may not involve multiple time points but is defined by manipulation rather than repeated measurement.
