Each of the columns in the following table are explained in the list below. Each column header (A, B, C, etc. in bold) corresponds to a list item.

A B C D E F
0-1 A .09 .18 .03 -.29
B .23 .35 .05 -.25
C .68 .47 .92 .40*
Other .00 .00 .00

Column Explanations:

  • Sequence Number: '0-1' refers to the first item. The second item would be have a sequence number of '0-2'.
  • Individual Distractor Statistics: The distractors are listed as 'A', 'B', 'C' and 'Other'. While 'A', 'B' and 'C' are self-explanatory, 'Other' is where the statistic program places candidates who leave an item blank or select more than one answer. In most cases, you will see a zero in these fields.
  • This shows the percentage of candidates who selected each character.
  • The computer program divides the candidate population into groups based on how they perform on the entire test. This column shows the percentage of the low group who selected each distractor.
  • This column shows the percentage of the high group who selected each distractor.
  • This column shows the individual distractor point by serial. Incorrect answers are strongly negative, while correct answers are positive.
