Intervening variable is also known as ______ variable.
(A) Dependent
(B) Control
(C) Systematic
(D) Cumulative
Correct Ans: (B)
Explanation:
An intervening variable plays a crucial role in research by affecting the relationship between an independent and a dependent variable. It is also known as a control variable because researchers monitor or account for its influence. Without considering intervening variables, research findings may be misleading or incomplete.
For example, in media effects research, a study might examine how news exposure (independent variable) influences public trust in journalism (dependent variable). However, an intervening variable, such as media literacy, could impact this relationship. People with higher media literacy may interpret news differently, leading to variations in trust levels.
Intervening variables help researchers identify hidden factors that influence outcomes. They often appear in psychological studies, audience research, and communication theories. Controlling these variables ensures that the observed relationship between the main variables is not distorted by external influences.
Moreover, researchers use statistical methods like regression analysis to measure the effect of intervening variables. By isolating their impact, they can determine whether the main relationship remains strong or weak.
In conclusion, an intervening variable, also known as a control variable, is essential in research. It clarifies complex relationships and ensures accuracy in findings, especially in mass communication and media studies.
