Alternate forms of the test were also developed and examined in subsequent studies published in the peer-reviewed journals. The alternate test forms were titled THING 1 and THING 2. (Remember to refer back to your Psychological Testing and Assessment text for information about using and interpreting a coefficient of reliability.)
• Internal consistency reliability coefficient = .92
• Alternate forms reliability coefficient = .82
• Test-retest reliability coefficient = .50
• In your post:
• Describe what these scores mean.
• Interpret these results individually in terms of the information they provide on sources of error variance.
• Synthesize all of these interpretations into a final evaluation about this test's utility or usefulness.
• Explain whether these data are acceptable.
• Explain under what conditions they may not be acceptable and under what conditions, if any, they may be appropriate.
