What is analytical cross-sectional study?
An analytical cross-sectional study is a type of quantitative, non-experimental research design. These studies seek to “gather data from a group of subjects at only one point in time” (Schmidt & Brown, 2019, p. 206).
Is cross-sectional data primary or secondary?
However, in modern epidemiology it may be impossible to survey the entire population of interest, so cross-sectional studies often involve secondary analysis of data collected for another purpose. In many such cases, no individual records are available to the researcher, and group-level information must be used.
