Controlling extraneous factors to reduce behavioral variability is necessary in order to be sure that any change in responding during a particular phase is due only to the ______.
A) extraneous variable
B) independent variable
C) dependent variable
D) inherent variable

Question

Quizplus · Accepted Answer

Controlling extraneous factors is necessary to ensure that any change in responding during a particular phase is due only to the independent variable, which is the factor being manipulated in the experiment. Therefore, the correct answer is the independent variable (B). The dependent variable (C) is the variable being measured in the experiment and is not relevant to this question. The inherent variable (D) is not a commonly used term in experimental design. The extraneous variable (A) is the variable that needs to be controlled, not the variable that researchers are interested in manipulating.
