Question

Quizplus · Accepted Answer

Experimental control is the process of removing or minimizing the impact of extraneous variables on the outcome of the study. This is done through various measures such as randomization, blinding, and standardizing procedures to ensure that the results are attributable to the manipulation of the independent variable rather than any other factors. Sample assignment, sorting independent variables, and determining dependent variables are important tasks in research design but are not specific to controlling extraneous variables.
