1. Describe an example of test-retest reliability. Test-retest reliability involves conducting the same test with the same respondents at different points in time. For example, a group of participants is given a personality test and then the same is tested at a later time, perhaps a month or a year later (Kline, 2005).2. If the correlation between test scores at Time 1 and Time 2 is 0.85, how would it be interpreted? The correlation between Time 1 and Time 2 is 0.85 and is significant (0.000); however, if the reliability drops from 0.85 a decision must be made whether the test should be re-tested (Kline, 2005).3. What are some problems associated with reliability assessed using the test-retest method? The problem with test-retest reliability is that it requires the same participants at different times; which makes replication difficult (Kline, 2005). For example, there may be fewer participants. Furthermore, the longer the interval between tests, the greater the possibility of variation in results; furthermore, participants have the opportunity to learn the test a second time and can create different results (Kline, 2005). Finally, it is very expensive to run consecutive tests (Kline, 2005).4. Under what circumstances is reliability assessed by the test-retest method most appropriate? I think the best use of test-retest reliability is when measuring the consistency of a test whose results must be consistent and stable over time, such as intelligence or personality ( Kline, 2005).5. What are the strengths and disadvantages of alternative forms of trustworthiness? Alternative forms of reliability may represent an even more costly approach. One of the disadvantages is that the "equality of elements" becomes questionable and that...... half of questions on paper. I think the most important thing I learned in this assignment is to determine the most effective way to evaluate reliability based on the needs of the study and the time available to complete the project. Reliability is as much a part of studying as finding the answers is. Without it, we can't guarantee that our test was intended to capture what it was intended to do. Works Cited Kline, T. (2005).
