Discussion
In which type of reliability methods do the chances of error variance remain high due to time sampling?
Answer: A
Test-retest reliability carries a high chance of error variance from time sampling, because the same test is given twice with an interval and conditions may change. Split-half and interscorer reliability depend on content and scorer, and alternate form reliability depends on the forms used. In the test-retest method the same test is given to the same people on two occasions, and the correlation between the two sets of scores is the reliability, so changes in the person or the situation over time lower it.
