ndrés is interested in testing a new measure of extroversion in college students. He gives the measure to a group of 20 college students and then administers it again 3 and 6 months later. He finds that some of the students who initially reported moderate levels of extroversion report lower levels 6 months later, while several of the students who initially reported low levels of extroversion report higher levels 6 months later.With what type of reliability may Andrés’ measure have a problem?

Solution
The type of reliability that Andrés' measure may have a problem with is test-retest reliability. Test-retest reliability is a measure of the consistency of a psychological test or assessment. This type of reliability is used to assess the consistency of a test across time. This means that a person should get the same or a very similar score if they take the test again under the same conditions. If Andrés' measure is showing different levels of extroversion for the same students at different times, then it may not be reliably measuring extroversion.
