Final Answer:
To ensure a standardized testing environment and reduce fatigue. Thus the correct option is (a).
Step-by-step explanation:
Subtests are administered in a specific order primarily to maintain a standardized testing environment and minimize the impact of fatigue on the test-takers. Standardization is crucial in psychological and educational assessments to ensure fairness and consistency across different test sessions and for different individuals. Administering subtests in a predetermined order helps control variables that could otherwise affect the reliability and validity of the test results.Thus the correct option is (a)
When subtests are arranged in a specific sequence, it helps create a consistent testing experience for all participants. This consistency is essential for comparing individual performance to established norms and making meaningful interpretations of the results. Moreover, a standardized testing environment promotes fairness by minimizing external factors that could disproportionately influence the performance of certain individuals.
Additionally, the consideration of fatigue is essential in test administration. Fatigue can negatively impact cognitive functioning and concentration, potentially affecting a test-taker's performance. By strategically ordering subtests, test administrators aim to distribute cognitive demands more evenly, reducing the likelihood of fatigue influencing results. This thoughtful approach enhances the accuracy and reliability of the assessment, contributing to the overall validity of the test.
