Answer :
Answer:
Reliability
Explanation:
A science teacher is unsure about the scores for the second batch of tests. Student scores on this last test are not at all similar to their scores on the test conducted two weeks ago. The teacher is confronted with RELIABILITY as a problem with testing.
RELIABILITY is the degree to which an assessment tool produces stable and consistent results.
Types of Reliability includes Test retest reliability which is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals.
Answer: Reliability
Explanation: Establishing consistent similarity in performance, test or behavior is used to measure the reliability of a observed result. In the context above, the teacher had conducted two different test at separate times. However, the teacher is skeptical about the observed result in the result obtained by the student in the latest test as it does not exhibit consistency or similarity, therefore leading to thought that the test result isn't reliable due to the dissimilar nature of the two test results.
