What is an important feature of experimental research compared to observational research?

An important feature of experimental research is its ability to establish causation. This is achieved through the manipulation of independent variables to observe the effect on dependent variables while controlling for other factors. This controlled environment allows researchers to draw conclusions about cause-and-effect relationships, which is a fundamental aspect of experimental studies.

In contrast, observational research does not involve manipulation of variables; instead, it focuses on observing and recording behavior or phenomena as they occur naturally. While observational research can identify correlations and associations, it cannot definitively determine causal relationships due to potential confounding variables that are not controlled in the same way as in experimental research.

Thus, establishing causation is a key distinguishing characteristic of experimental research that contributes to its robustness in scientific inquiry.
