What is a characteristic of non-experimental research?

Non-experimental research is characterized by its observational approach, rather than manipulating variables or imposing experimental controls. The inclusion of correlation studies and case studies is a key feature, as these methods allow researchers to explore relationships between variables without direct intervention.

In correlation studies, researchers assess the degree and direction of relationships between two or more variables, while case studies provide in-depth analysis of a single subject or group, capturing complex phenomena in real-world contexts.

On the other hand, manipulating independent variables or requiring random assignment are characteristics of experimental research, which seeks to establish causation rather than merely observe associations. Additionally, non-experimental research can be both qualitative and quantitative, not strictly limited to one methodology. Therefore, the inclusion of correlation and case studies accurately represents a defining feature of non-experimental research.
