Is validity is a prerequisite of reliability?

No, validity is not a prerequisite of reliability. Reliability refers to the consistency or stability of a measure, while validity refers to the accuracy of the measure in assessing what it is intended to assess. A measure can be reliable but not valid, meaning it consistently measures something but not necessarily what it is intended to measure.


What are the principles of high quality assessment?

High quality assessment should have these characteristics: 1. Purposeful 2. Clear/Appropriate Targets 3. Appropriate Methods 4. Validity 5. Reliability 6. Fairness 7. Positive consequences 8. Practicality and Efficiency


What is the cause and effect of hypothesis?

The cause of a hypothesis is a research question or problem that needs to be addressed. The effect of a hypothesis is that it provides a proposed explanation or prediction that can be tested through research and experimentation. This testing helps to determine the validity and reliability of the hypothesis.


What are reliability indicators?

Reliability indicators are measures used to assess the consistency and stability of data or results. Common reliability indicators include test-retest reliability, internal consistency (Cronbach's alpha), inter-rater reliability, and split-half reliability. These indicators help researchers determine the trustworthiness and accuracy of their measurements.


Methods of calculating validity in psychological test?

Two common methods for assessing validity in psychological tests are content validity, which involves examining whether the test adequately covers the content it is supposed to measure, and criterion validity, which looks at how well a test predicts or correlates with an external criterion. Other types of validity include construct validity, which assesses whether the test measures the theoretical construct it claims to measure, and face validity, which considers if the test appears to measure what it intends to measure.

In what situations would reliability be more important that validity?

Considering in test-scoring "reliability" refers to the consistency of the test scores, and "validity" refers to the accuracy of the interpretations made from those scores, then reliability is possible without validity, although validity is not possible without reliability.

What are the differences between validity and reliability?

validity is whether the results are valid so the data has no mistakes of as such in it whereas reliability is the dependability; when the results you have are accurate and are of enough quality.

Why is validity harder to establish and evaluate than reliability?

Validity refers to the accuracy of a measure in assessing what it intends to measure, while reliability refers to the consistency of the measure. Establishing validity involves multiple factors such as construct validity, content validity, and criterion validity, making it more complex than evaluating reliability. It requires more evidence and validation processes to ensure that the measure is actually measuring what it is supposed to.


What is the most important when judging the quality of a scientific theory?

validity and reliability


What procedures can be followed to ensure the reliability validity currency and accuracy of data information used by an organisation?

Double checking and verification are some of the procedures that can be followed by an organization to ensure reliability,validity and accuracy of the data information.


What is the importance of test reliability and validity?

Test reliability ensures consistent results when the test is repeated, indicating the test is reliable and consistent. Test validity ensures that the test measures what it is supposed to measure, providing meaningful results. Both reliability and validity are essential for ensuring the accuracy and effectiveness of a test in assessing the intended construct or concept.


What is a test that measures or predicts what is supposed to is said to have a high degree of what?

validity is the answer....


What addresses the questions of what a test measured and how well it measured it?

A validation study addresses the questions of what a test measured (construct validity) and how well it measured it (criterion validity and reliability). Construct validity examines if the test measures the intended construct or trait. Criterion validity examines if the test results predict or correlate well with other measures. Reliability examines the consistency and stability of the test scores over time.
