When a user views the gradebook, statistics display for each graded item. The mean, standard deviation, median, range and number of entered (non-blank) scores display below the student's scores for each item as shown below. The Grader's computation of the statistics only includes scores for which there is a value present, this includes zeros, but excludes blank scores. Statistics also display for the numeric totals and the letter grades. The letter grade statistics are the letter grades that correspond to the numeric totals, as determined by the grade ranges table. Statistics update in real time as the teacher enters or edits grades.
