Question 6

When is test-retest reliability calculated?

Accepted Answer

When assessing the consistency of scores over time

Question 7

Which of the following methods is used to calculate internal consistency reliability?

Accepted Answer

Cronbach's alpha

Question 8

What is the primary purpose of assessing reliability in educational assessments?

Accepted Answer

To ensure that assessment results are consistent and accurate

Answer

To determine the difficulty level of an assessment

Question 9

Explain how an assessment can be reliable but not valid. Provide an example to illustrate your explanation.

Accepted Answer

Reliability refers to the consistency of an assessment, while validity refers to the accuracy of the assessment. An assessment can be consistent in its results, but if it is not measuring what it is intended to measure, then it is not valid.

Validity and reliability are synonymous terms in assessment.

Answer

An assessment cannot be reliable without also being valid.

Answer

Higher student grades

Answer

Increased student motivation

Question 17

What is the difference between inter-rater reliability and test-retest reliability?

Accepted Answer

Inter-rater reliability measures the consistency of scores between different observers, while test-retest reliability measures the consistency of scores over time.

Answer

Inter-rater reliability is more important than test-retest reliability.

Question 18

What are some techniques that can be used to improve the reliability of an assessment?

Accepted Answer

Using clear and concise instructions, providing training to observers, and using multiple raters.

Answer

Making the assessment more difficult

Answer

Reducing the time limit for completing the assessment

Question 19

What is the relationship between validity and reliability?

Accepted Answer

A reliable assessment is not necessarily valid, but a valid assessment must be reliable.

Answer

Validity is more important than reliability.

Answer

Reliability and validity are synonymous.

Question 20

What is the ethical importance of ensuring the reliability of assessments?

Accepted Answer

It helps to ensure fair treatment of students and accurate decision-making based on assessment results.

Answer
