Here is another simplified presentation about the process of Distracter Analysis in Educational Assessments. Included here are terminologies, reminders, definitions, as well as process in conducting it. Thank you. Namaste.

5. is an extension of item
analysis, using techniques
that are similar to item
difficulty and item
discrimination

6. However, we are no longer
interested in how test takers
select the correct answer, but
how the distracters were able to
function effectively by drawing
the test takers away from the
correct answer

7. However, we are no longer

8. They are plausible but
incorrect options that are
often developed based upon
students’ common
misconceptions or
miscalculations

11. Distractor analysis can
be a useful tool in
evaluating the
effectiveness of the
distractors

12. It is important
for us to be
mindful of the
distractors
that we use in a
multiple choice
format test

13. as when
distractors
are not
effective, they
are virtually
useless
