Exploring the cross-sectional study design, this overview highlights its use in psychology and public health to analyze population data at a single point in time. It outlines the methodology, types of cross-sectional studies—descriptive, analytical, and serial—and their applications. The benefits, such as efficiency and cost-effectiveness, are weighed against challenges like the inability to establish causality and potential sampling bias.
