In experimentation, what do researchers do with all other variables?

In experimentation, researchers focus on controlling all other variables to ensure that the effects observed in the study are directly attributable to the independent variable being tested. By controlling extraneous variables, researchers minimize potential confounding factors that could distort results and lead to incorrect conclusions. This control can involve various techniques, such as random assignment, holding variables constant, or using control groups, all of which aim to isolate the relationship between the independent and dependent variables. This rigorous approach is essential in establishing cause-and-effect relationships, making the findings of the research more reliable and valid.

Neglecting other variables could lead to misleading results, while simply observing or testing them wouldn’t adequately rule out their influence on the experiment's outcome. Therefore, the emphasis on control clearly highlights the importance of proper experimental design in achieving valid, interpretable results.
