Education QUESTION #6754
Question 1
Two teachers score the same set of 30 essay responses independently. Teacher A's scores and Teacher B's scores correlate at r = 0.55. This most directly indicates a problem with which measurement property?
  • Content validity of the essay prompt
  • Inter-rater reliability (a form of consistency of ratings)✔️
  • Split-half reliability of the essay test
  • Criterion validity of the essay assessment
Correct Answer Explanation
Inter-rater reliability (inter-scorer reliability) measures the consistency of scores assigned by two or more independent raters. A correlation of 0.55 is low, indicating significant scorer disagreement. This is a reliability problem, specifically related to the consistency-of-ratings dimension, not content or criterion validity.
