Dr. Karlyle has developed a new logical reasoning test. She administers the test to a group of incoming freshman. The next year, she tests the same students, who are now sophomores, and finds that the overall correlation between the two sets of scores is -0.25. Based on this information, Dr. Karlyle should conclude that her new test
A) has been poorly standardized.
B) will have high criterion-related validity.
C) has low test-retest reliability.
D) has high test-retest reliability.

Question

The negative correlation of -0.25 suggests that there is a low test-retest reliability, meaning that the scores from the first year are not consistent with those from the second year. This could be due to factors such as measurement error or changes in the students' abilities over time.
