Interrater reliability measures the consistency or agreement between two or more observers when using a standardized instrument. This scenario describes two observers using the same instrument, making interrater reliability the appropriate measure for comparison of their scores. The other options are not relevant to this scenario - face validity is the degree to which a measure appears to accurately assess the intended construct, split-half reliability is a method of assessing reliability that involves splitting a test into two halves and comparing the scores, and construct validity refers to the degree to which a measure accurately reflects the underlying construct being measured.
