A variable that creates an alternative explanation of results is identified as
(A) Alternative variable
(B) Artifact
(C) Predictor variable
(D) Antecedent variable
Correct Ans: (B)
Explanation:
An artifact in research refers to a variable that introduces an alternative explanation for results. It can distort findings, leading to misleading conclusions. Researchers must identify and control artifacts to ensure accurate interpretations.
Artifacts often arise due to external influences rather than the independent variable being studied. For example, in an experiment on media effects, researcher bias, participant expectations, or environmental conditions can affect results. These unintended factors create confusion about the true cause of an observed effect.
One common type of artifact is the Hawthorne effect. This occurs when participants change their behavior simply because they know they are being observed. Another example is experimenter bias, where a researcher unintentionally influences participants’ responses. Both cases introduce alternative explanations, reducing the reliability of results.
Moreover, artifacts can affect survey-based research. Leading questions, unclear wording, or respondent fatigue can skew responses. In content analysis, coder bias or inconsistent classification can also introduce artifacts. Therefore, researchers must design studies carefully to minimize such errors.
To reduce artifacts, researchers use techniques like randomization, double-blind procedures, and control groups. These methods help isolate the true effect of the independent variable while reducing external influences. Additionally, proper sampling and clear research design enhance study credibility.
In conclusion, artifacts create alternative explanations that can mislead research findings. Identifying and controlling them ensures the validity and reliability of results. Researchers must remain cautious to produce accurate and meaningful conclusions in communication studies
