The difference in results suggests that the test does not produce consistent outcomes over time, indicating a lack of reliability. Reliability refers to the consistency of a measure, and if the test results vary significantly from the beginning to the end of the term without an apparent reason, it suggests that the test may not reliably measure what it intends to, in this case, aggression.
