Assertion A: The concept of the single variable provided a sound approach to experimentation in the behavioural sciences.
Reason R: The earliest assumptions of experimental research were based on what was known as the 'law of the single variable'.
In the light of the above statements, choose the most appropriate answer from the options given below
Assertion A claims the single variable concept was a sound approach for experimentation in behavioral sciences. This is incorrect. Behavioral science often involves complex phenomena with numerous interacting variables. Focusing solely on one variable can oversimplify and potentially yield misleading results.
Reason R states that early experimental research assumptions relied on the 'law of the single variable'. This is correct. This principle suggests manipulating only one variable at a time while controlling others, aiming to isolate cause-and-effect relationships. It was a foundational concept in developing rigorous experimental methods.
Based on the analysis, Assertion A is incorrect because the single variable approach is often insufficient for complex behavioral studies. Reason R is correct as the 'law of the single variable' was a fundamental principle in early experimental research design. Therefore, R does not explain A, and the correct choice is that A is incorrect while R is correct.
