Question

Quizplus · Accepted Answer

In an experiment, researchers manipulate one variable (the independent variable) to determine if it causes a change in another variable (the dependent variable), allowing them to isolate cause-and-effect relationships. Observational studies, on the other hand, involve observing subjects without manipulation, making it harder to establish causality.
