Non-distractors are answers that did not distract the

student from the correct

answer.

The standard deviation reflects

the amount of points that deviate from the

mean.

The KR20 reflects how likely it is that a student

will do as well on the second half of the exam as s/he did on the first half of the exam. An

exam with a high KR20 yields reliable student

scores. The KR20 ranges from a low of 0 to a high

of 1.

This is the percentage of students who answered this item correctly.

This is the percentage of high scoring students who answered this item correctly.

This is the percentage of low scoring students who answered this item correctly.

A high point biserial coefficient means that high scorers answered the item

correctly more frequently than low scorers. A low point

biserial coefficient means that high scorers answered the

item incorrectly more frequently than low scorers.
