Item Analysis | MCQs

Explanation

Explanation

The most significant advantage of true/false items is wide sampling.

Explanation

The use of many selected responses in a test can indeed provide good objectivity.

By offering multiple options for each question, it helps reduce potential bias and subjectivity in grading, as the answers are typically clear and objective.

Explanation

"Effective testing of higher cognitive levels" is not typically considered a strength of multiple choice items.

While multiple choice items are excellent for testing recall and understanding of factual knowledge, they are less effective at assessing higher cognitive levels such as critical thinking or application of concepts.

Explanation

Essay type tests have advantages over objective tests because they provide opportunities to organize knowledge.

Unlike objective tests, which often require selecting from predetermined options, essay tests allow students to demonstrate their understanding by structuring and articulating their thoughts in their own words.

This format encourages deeper thinking, critical analysis, and the integration of diverse ideas, leading to a richer and more comprehensive assessment of learning.

Explanation

The best measure to avoid guessing in a structured test is indeed to use completion items.

Completion items require test-takers to provide a complete answer rather than selecting from multiple options, thus reducing the possibility of guessing compared to multiple-choice items.

Explanation

Multiple-choice questions cover a broad sampling of content within a subject area, allowing for assessment across various topics or concepts.

Explanation

A difficulty index of 5% typically indicates that the item is relatively difficult.

Explanation

Item Analysis focuses on finding out various aspects of test items, including their Facility index (difficulty level), Discrimination powers (how well they discriminate between high and low performers), and the Effectiveness of distractors (incorrect options). 

Explanation

In norm-referenced tests, the best item is one whose difficulty is near 50.

This means that the item has an equal chance of being answered correctly or incorrectly by the test takers, making it a good discriminator between high and low performers.

Items with extreme difficulty levels (near zero or near 100) may not effectively differentiate between students' abilities.
