Test Reliability | MCQs

Explanation

If a criterion-referenced test is reliable, scores from the test are consistent, meaning they provide stable results over repeated administrations.

This consistency ensures that the test accurately measures what it intends to assess, enhancing its utility and validity in evaluating specific criteria or standards.

Explanation

Essay tests tend to have the lowest reliability compared to other types of tests.

This is because essay responses can vary greatly depending on the interpretation of the grader, making it more difficult to ensure consistent scoring and thus lower reliability.

Explanation

The quality of a test to give consistent scores when administered at different times is called reliability.

Explanation

If the sample size of the questions in the test is sufficiently large, the quality of the test is referred to as Adequacy.

This suggests that the test adequately represents the content or construct it aims to assess, providing a comprehensive measure of the targeted domain.

Explanation

The most commonly used guessing correction formula to predict and control is S = R - (W/N - 1), where:

• S represents the corrected score
• R represents the raw score
• W represents the number of incorrect options selected by the student
• N represents the total number of options in the multiple-choice question.

Explanation

A discrimination value of more than 0.4 indicates that the item is considered to be "acceptable" in terms of its ability to differentiate between high-performing and low-performing students.

This means that the item effectively discriminates between individuals who possess the desired skill or knowledge and those who do not.

Such items are valuable for assessing the targeted attribute with clarity and precision, contributing to the overall effectiveness of the assessment process

Explanation

Marking will be more reliable in Multiple Choice Questions (MCQs).

MCQs offer a structured format with clear answer choices, reducing subjectivity and variability in grading compared to open-ended formats like essays or short answer questions.

MCQs allow for easier and more consistent scoring, enhancing reliability in assessment.
