A: in a box and whisker plot the median is found by looking at the line between Q1 and Q3. so in Class #1 the median seems to be 80%. And in class #2 in seems to be about 75%
B: Range is defined as the the highest and lowest scores, so in class #1 it would be ~72%-85%. therefore class #2 would be 70%-90%
C:The highest grade can be found by looking at which class had the highest percentage. The max of class #1 is ~85% while the max of class #2 is 90%, so class 2 had the highest score
D: IMO class #1 had a better overall score. While class #2 had the highest score it also had the lowest pulling the mean/average down. Also we can see from the chart that the median is much higher in class #1
Hope this helps :)
