%description
Functions for analyzing multiple choice items. These analyses include the
convertion of student response into binaty data (correct/incorrect), the
computation of the number of corrected responses and grade for each
subject, the calculation of item difficulty and discrimination, the
computation of the frecuency and point-biserial correlation for each
distractor and the graphical analysis of each item.
