Often described as a snapshot of a population in a certain point in time. because exposure and outcome are determined simultaneously for each subject. There are four basic types of research design: 1) case studies 2) cross- sectional designs 3) (and thus) it benefits from the prior development of theoretical propositions to guide data collection and analysis.

When we conduct a study using cross-sectional design, we take a group of samples from a set, or continuum, to see if there are any differences in the section of the continuum.

Also, this type of analysis does not suffer from participant attrition as longitudinal research does. Repeated cross-sectional study is a related term where a cross-sectional study is repeated at regular or irregular intervals, but the sample population may not be the same for different time points. » Design, applications, strengths and weaknesses of cross-sectional, analytical studies, and intervention studies (including randomised controlled trials).Design, Application, Strengths Weaknesses of Cross-Sectional Studies.

What are the Benefits of Cross-Sectional Studies?One survey is much easier to manage than multiple, from design to collecting responses to analyzing your data to acting on the results. In medical research and social science, a cross-sectional study (also known as a cross-sectional analysis, transverse study, prevalence study) is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time—that is, cross-sectional data. Cross-sectional studies involved studying groups of participants in different age groups at the same point in time.The problems of this type of design can often override the benefits.
