Interpretation of Analyses with Omitted Items or Multiple Correct Answers Per Item
You requested
that we omit one or more items from your exam key, and/or that multiple
responses per item should be scored as correct. Note that the following
conditions will occur:
- The scores printed on the answer sheets will not accurately
reflect the scoring with multiple correct response items. It will be
accurate when items are omitted.
- The test statistics and corresponding score rosters also
will reflect the accurate scores, counting omits and multiples.
- When item(s) are omitted, the item analysis program
will reflect the same test statistics as given in the score roster/test
statistics program (assuming each item is worth one point). Any omitted
item(s) will not appear in the individual item analyses portion
of the output.
- When items are omitted, the error sheets for the students
will indicate that every student "missed" the omitted
item(s), and that the correct response is "X." This
only maintains proper item numbering; the student's test score is correct.
- When item(s) have multiple correct responses, one of the correct
responses arbitrarily is chosen for the item analysis key. Therefore,
the mean printed in the test statistics from the item analysis program
will be lower than the mean printed in the test statistics/score roster
program.
- When item(s) have multiple correct responses, only one of
the correct responses will be chosen for the student's error sheets.
Therefore, if a student answers one of the correct responses not chosen,
the error sheet will indicate that the item was "missed," and
the total score will be incorrect.
