Transverse analysis, cross-sectional analysis, and prevalence studies are other names for this sort of research. Even though it doesn't entail running experiments, cross-sectional research is frequently used by academics to understand outcomes in the physical and social sciences as well as many business domains.
<h3><u>Cross-sectional study characteristics.</u></h3>
A cross-sectional study must have, among other things:
- With the same set of data over a predetermined time frame, researchers can conduct a cross-sectional study.
- While similar studies could focus on the same variable of interest, each one looks at a different group of people.
- Contrary to longitudinal investigations, where variables can vary over the course of extended research, the cross-sectional analysis evaluates themes during a single instance with a fixed start and stopping point.
- In cross-sectional studies, one independent variable and one or more dependent variables can both be examined.
