experimental research
Hypothesis-testing scientific work
Experimental research is investigation that tests hypotheses by manipulating variables under controlled conditions.
The researcher changes one factor while holding others constant to observe effects: The experimental research showed that the drug reduced symptoms compared to placebo.
Distinguished from observational research, where variables aren't deliberately manipulated.
