Suppose Q1 and Q7 have been rescaled to 10 points maximum for each one, but blank scores have not been replaced with zeroes. Suppose the following formula is used to determine the quiz score average out of 100 points for the first student and copied to the rows for other students. The lowest two quiz scores are to be dropped. The formula: =(SUM(D8:R8)-SMALL(D8:R8,1)-SMALL(D8:R8,2))/(COUNT(D8:R8)-2)*10 1) Gives the correct quiz average for all students 2) Understates the quiz average for some students 3) Overstates the quiz average for some students 4) Understates or overstates the quiz average
