Document Summary
Both the behaviour of the examiner and his/her relationship to the test taker can affect test scores. In one study reported more than 50 years ago, 1st through 7th grade children were given the. The examiner"s rapport had little effect on the scores of the younger children. Another study compared scores obtained by examiners who made approving comments (such as. Good or fine ) with scores obtained by examiner who used disapproving comments or neutral comments: children who took the test under a disapproving examiner receiver lower scores than did children exposed to a neutral or an approving examiner. Studies show that familiarity with the test taker, and pre-existing notions about the test taker"s ability can positively or negatively bias test results. For example, in telephone interviews, some vendors have substituted face-to-face interviewers with the use of a remote electronic voice - since the electronic data collection is cheaper, but the results in more variability and more error.
