If a student get same 42 marks out of 80 awarded by different examiners in a test of Mathematics, this shows which characteristics of evaluation out of following:

Correct option is C

S. Ans. (c) Reliability

Solution:
Reliability in evaluation refers to the consistency of the results obtained. When a student is awarded the same marks (42 out of 80) by different examiners, it indicates that the evaluation method or tool consistently measures the same result irrespective of who evaluates the student. This consistency demonstrates the reliability of the test.

Explanation of other options:

1. (a) Objectivity: Refers to the absence of bias in assessment. While objectivity may contribute to reliability, the scenario here specifically highlights consistent results, which is a marker of reliability.
2. (b) Validity: Refers to whether the test measures what it intends to measure. While the test could be valid, the information given does not confirm whether the test accurately assesses the intended learning objectives.
3. (d) Practicability: Refers to the feasibility of conducting the test in terms of time, resources, and effort. This is unrelated to the consistency of scores.

Information Booster

1. Reliability ensures consistent results across different conditions or evaluators.
2. A reliable test minimizes random errors in measurement.
3. High objectivity contributes to reliability, but they are not identical.
4. A valid test must also be reliable, but a reliable test is not necessarily valid.
5. Consistency over time is known as test-retest reliability; consistency across evaluators is inter-rater reliability.
6. Reliability is essential for the credibility of evaluation results in education and research.

Additional Information

• (a) Objectivity: Focuses on eliminating subjectivity in the evaluation process. Tests like multiple-choice questions are highly objective.
• (b) Validity: Ensures that the test is measuring the intended learning outcomes. For example, a math test should measure mathematical skills, not linguistic abilities.
• (c) Reliability: Indicates the stability and consistency of the test results across different instances. For example, marks awarded in a standardized math test by various evaluators should remain consistent.
• (d) Practicability: Refers to the ease of implementation of the test, such as whether it is cost-effective and time-efficient.
