   Question

   The test-retest reliability of a psychological stress test for pilots is .50. What is a plausible explanation for this low reliability?

   
   
   1. FALSE: The interval between the two measurements is long, so the true scores of the pilots have changed.
   2. FALSE: The interval between the two measurements is long, so the variance in measurement error differs across measurements.
   3. TRUE: Both A and B offer an explanation for the low reliability
   4. FALSE: A nor B offer an explanation for the low reliability.
   
   

   Solution

   When the interval between the two measurements is long, both the true scores and the variance in measurement error are subject to change. This method of reliability makes the assumption that both remain equal over the two measurements.

   
   
   1. False
   2. False
   3. True
   4. False
