Control is an important characteristic of: Options: (a) Introspection method (b) Observation method (c) Experimental method (d) Case study method ✅ Correct Answer: (c) Experimental method Explanation: The experimental method in research involves systematic manipulation of independent variables to observe effects on dependent variables, while controlling other factors. Control is essential to eliminate confounding variables and ensure valid, reliable results. Introspection, observation, and case study methods focus on description, self-report, or in-depth analysis but do not involve strict control over variables. Experiments are widely used in psychology, education, and social sciences to establish cause-effect relationships. In education, controlled experiments help evaluate teaching strategies, learning interventions, or behavioral outcomes, making this a key PPSC research methodology topic. 10 Related Facts: 1.
