Different statistics contribute different information to the assessment of test results. For example, if your aim is for all students to master a certain subject, you will want to see a narrow range with scores in the 90s. On the other hand, if you want to differentiate between student performance, you will probably want to see a wider score distribution. Therefore, depending on your needs, you may be interested in different statistics at different times.

You may checkmark as many of the statistics as interest you, and they will appear below the rows of other test data, such as Date, Possible [points], etc. Like other display choices, they can be changed again at any time. In computing Variance, GradeQuick assumes that the class represents the total population. Therefore, GradeQuick calculates variance as the sum of the squares of the deviations from the mean divided by n, the number of students in the class.
