Please note the following: Column A (rows 2-66) represents the responses of the 65 students who completed the exam. Row 1 (columns B-BN) represent the individual exam items. Column BP shows the exam grade each student received. Rows 82-84 show the point-biserial index for the correct answer (shaded in green). Rows 85-88 show the point-biserial index for each individual multiple-choice option for the item (shaded in blue). Rows 90-104 (columns A & B) demonstrate the overall test statistics.
