Question

Dr. Abaee is developing a new intelligence test. She gives her test to a group of 100 participants and records their scores. Six months later, she retests the same participants on the test and finds that their scores match well with the scores they earned when tested six months earlier. What can we conclude about Dr. Abaee’s test based on this study?

Types of reliability:
