A. Usability
B. Differentiability
C. Objectivity
D. Reliability
Answer is = A
You are absolutely right! Out of the given options, the quality of a test that considers factors like ease of time, cost, administration, and interpretation is called:
A. Usability
Here’s why the other options are not directly related to these aspects:
- Differentiability: This refers to the ability of a test to distinguish between high and low achievers, which doesn’t encompass the broader concept of ease of use.
- Objectivity: Objectivity focuses on minimizing scoring bias, not necessarily the time or cost associated with the test.
- Reliability: Reliability is concerned with the consistency of scores, which doesn’t directly address the ease of administration or interpretation.
Usability, on the other hand, is a broader concept that considers the user-friendliness of a test from various perspectives, including:
- Time: Can the test be administered and completed within a reasonable timeframe?
- Cost: Is the test cost-effective to develop, administer, and score?
- Administration: Is the test easy to administer for educators or test administrators?
- Interpretation: Are the test scores and results clear and easy to interpret for teachers, students, or other stakeholders?
In conclusion, usability is the most fitting choice because it encompasses the practical aspects of a test, considering the time, cost, ease of administration, and interpretability of the results. While validity, reliability, and objectivity are crucial for ensuring the quality of the assessment itself, usability focuses on the practical considerations that make the test user-friendly and efficient to implement.
