Through which research method, the manipulation of an independent variable and its effect on dependent variable is examined with reference to a hypothesis under controlled conditions?
Experimental research
The question involves identifying the research method where an independent variable is manipulated to observe its effect on a dependent variable under controlled conditions. This corresponds to experimental research. Let's explore why this is the correct answer:
-
Understanding Experimental Research:
- In experimental research, researchers manipulate one or more independent variables to determine their effect on one or more dependent variables.
- This is often done in a controlled environment to ensure that any observed changes in the dependent variable are solely due to the manipulation of the independent variable.
- It involves formulating a hypothesis and testing it through controlled experiments.
-
Examining the Other Options:
- Ex-post facto research: This method involves studying the effects of an experiment that has already taken place without any manipulation of variables by the researcher.
- Descriptive research: This approach involves observing and describing the behavior of a subject without influencing it in any way.
- Case study research: This type involves an in-depth analysis of a single case or a few cases, without manipulating variables.
-
Conclusion:
- Given that experimental research is characterized by the manipulation of variables and testing under controlled conditions, it fits the description provided in the question.
- Therefore, the correct answer is experimental research.
