A cross-sectional study spanning an age range of four years

Question

Quizplus · Accepted Answer

A cross-sectional study is a type of observational research design that analyzes data collected from a population or a representative subset at a specific point in time, so it could theoretically be completed in a single day. The age range of the population being studied is not related to the time required to complete the study, as the data collection process is focused only on a single time point. Cross-sectional studies do not yield information comparable to that of longitudinal studies, which involve collecting data from the same individuals over an extended period of time. While cross-sectional studies may be less costly and time-consuming than longitudinal studies, this is not always the case, as it depends on factors such as the size of the population being studied, the number of variables being measured, and the complexity of the analyses being conducted.
