Video Summary

A cross-sectional study is a type of observational study that assesses the relationship between exposures and outcomes at a single point in time. It can be used to study factors associated with an outcome. In a cross-sectional study, data are collected from a group of participants who have been followed for a certain length of time. Data are then analyzed to see if there is an association between the different exposures and the outcome measure. Cross-sectional are usually quick and cheap studies that help to sample large groups of people.
