Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). In the light of the above statements, choose the correct answer from the options given below.
Assertion (A):Experimental research allows you to eliminate the influence of many extraneous factors.
Reason (R):In experimental research variables are actively manipulated and the environment is controlled as far as possible.
ABoth A and R are correct and R is the correct explanation of A ✓ Correct
BBoth A and R are correct but R is not the correct explanation of A
CA is correct but R is not correct
DA is not correct but R is correct
Correct answer: (A) Both A and R are correct and R is the correct explanation of A
Explanation
Both A and R are correct and R correctly explains A.
Experimental research does allow the influence of many extraneous factors to be eliminated.
This elimination is possible precisely because variables are actively manipulated and the environment controlled.
Control of conditions is the mechanism by which extraneous factors are held constant or removed.
R thus states the reason that produces the outcome asserted in A.
Such control gives the experiment its high internal validity for causal inference.
