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.

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
