I am marking some 50-question, 4-choice, multiple choice tests. (About 
20 of them.)  The scores are noticeably low, 50%, 64%, 38%, 44%, 52%,...
I begin to worry that the marking key I am using may be mismatched with 
the version of the test I am marking.  After about nine papers marked, 
just as I am about to review the key against the actual questions,...I 
get a score of 84%.  I am immediately and intuitively certain the key is 
  the correct one and that this test group is just unusually low 
scoring.  Is there any science that discusses this sort of phenomena?
