       (reported on  5/10/2018
N              =   50
Average        =   160
Stand Deviation=   58
Median         =   160
Max range      =   300-333
Min range      =   0-50


As of now, class average is 658 pts and standard deviation 142. 
This would become approximately the border between a B and a C+.

RULE 1.
Exams at 25% of 333  = 83.25 receive an automatic F per Syllabus(Handout 1)

RULE 2.
Students are then groupped 'curve like' per half of standard deviation (~70-90pts).

Average         =  Sum of grades divided by number of exams
Stand Deviation =  Shows dispersion of grades. Roughly, 2/3 of the grades are
                   within 37 +/- 12 , and 95% within  37 +/-  2*12 if ave is 37 and std 12
Median          =  Half of the students got that much or less (and half, more than that).
