Reliability and Validity

Coursework Instructions:

This Discussion has 3 parts (questions). Be sure to answer all 3 parts. What does it mean when a tool of assessment is characterized as reliable? Under what conditions might one expect an otherwise useful tool of assessment to be unreliable? Consider the meaning of the following statement: “A test is valid.” How absolute or relative is test validity? Can a test be valid at one time and place with one population of test takers and invalid at another time, in another place, or with another group of test takers? Provide examples to illustrate. What does the Bible have to say about our responsibilities of discernment and inquiry in interpreting and drawing meaning from information (in this case, from test findings)? The student will post one thread of at least 350 words As a reminder, Liberty University updated the Student Honor Code to include artificial intelligence (AI). Below is the latest Liberty Way section (2023-24, p. 4) addressing academic dishonesty and the use of Artificial Intelligence. It includes, but is not limited to: • Unauthorized collaboration on any work for the course • Contract Cheating: Any involvement in the outsourcing of coursework to a third-party • Using unauthorized aids of any kind to create coursework without permission from the instructor. Unauthorized aids include, but are not limited to: • The coursework of others • Artificial Intelligence (AI) aids • Paraphrasing software • Any other aid that compromises the originality or authenticity of coursework • Any act that compromises exam integrity and/or violates exam protocols • Stealing, buying, receiving, selling, or transmitting coursework of any kind • Sabotaging another student's academic work • Facilitating or aiding in any act of academic dishonesty Please keep in mind that written assignments automatically go through a plagiarism detection tool called Turnitin. Turnitin scans your assignment for originality and artificial intelligence. Examples of artificial intelligence aids include but are not limited to ChatGTP, Bard, Grammarly, Adobe Firefly, Canva.ie, Cramly, and other equivalent forms of AI to create content for coursework. Rather than using unauthorized AI aids, consider using Microsoft Word's fairly new Editor tool to proofread for spelling and punctuation errors.

Reliability and Validity Name Institution Course and Code Professor Date Reliability and Validity Reliability of the Assessment Tool When a test tool is evaluated as reliable, it consistently leads to similar results when performed under the same conditions. Reliability, in general, is the property that shows the persistence and the continuity of the measurement process. A reliable assessment tool will result in the same or almost the same results upon subsequent administration to similar subjects or persons, assuming that the administration conditions do not change (Phillips et al., 2021). This consistency increases the confidence that the tool will measure what has been intended, yielding helpful and trustworthy results. Many factors may lead to an assessment tool becoming unreliable. These include inconsistencies in their administration procedures, such as variations in instructions given to participants or differences in testing objects' surroundings. Other factors that may lead to unreliability are differences in data, scoring mistakes, inadequate sample representation, and validity concerns (Darr, n.d.). For example, if the instrument does not sufficiently cover the factors it suggests evaluating or if the effects of external influences unduly influence the results, the reliability of the assessment tool can be doubted. Therefore, reliability must be achieved by paying particular attention to standardization, consistency, and validity at all levels of the assessment procedure. Test Validity "A test is valid" means that it accurately captures what it claims to capture. Validity means that the test accurately measures what needs to be measured. It should provide meaningf...
