Which of the following is not a characteristic of objective type test ?

Question

Accepted Answer

Option 3, "Have more validity," is identified as the correct answer because objective type tests, while reliable, often face challenges in fully capturing the depth and breadth of a subject's understanding, which can affect their validity. Validity refers to the extent to which a test measures what it claims to measure. Objective tests, such as multiple-choice questions, are typically designed to assess specific knowledge or skills. However, they may not always effectively evaluate complex cognitive abilities, critical thinking, or the application of knowledge in real-world scenarios. This limitation can impact the overall validity of the test, as it may not fully represent the construct it aims to measure.

Now, let's examine why the other options are incorrect:

1. **Needs more labour/effort to assess**: Objective type tests are generally easier and quicker to assess compared to subjective tests. They often involve straightforward scoring methods, such as answer keys or automated systems, which require less effort from the assessor. This makes them efficient for grading large numbers of test-takers.

2. **Have more reliability**: Objective tests are known for their high reliability. Reliability refers to the consistency of test results over time or across different raters. Because objective tests have clear, unambiguous questions and answers, they tend to produce consistent results, making them highly reliable.

4. **Easy to determine norms**: Objective tests facilitate the establishment of norms because they can be administered to large groups of people under standardized conditions. The uniformity in test administration and scoring allows for the easy collection and analysis of data, which can be used to determine norms and compare individual performance against a larger population.

In summary, while objective type tests are reliable and efficient, their validity can be limited due to their inability to fully capture complex cognitive processes, making Option 3 the correct choice.
