Cross-sectional studies gather data at a single point in time, providing a snapshot of the population being studied. They are commonly used in epidemiology, public health research, and social science research. In contrast, longitudinal studies follow individuals or groups over an extended period of time to track changes or trends, and case studies focus on one or a small number of individuals in depth. Exploratory studies refer to research that is conducted to gain a better understanding of a new or poorly understood phenomenon. Therefore, only cross-sectional studies fit with the described scenario.
