You can put this solution on YOUR website!
(68+72+53+77+57)/5=327/5=65.4 IS THE MEAN (AVERAGE) NUMBER OF BOOKS READ BY THESE 5 CLASSES.
53,57,(68),72,77 THE MEDIAN IS THE MIDDLE NUMBER WHEN ARANGED IN ASSENDING ORDER & FALLS IN THE FIRST PERIOD.
THERE IS NO MODE BECAUSE NO NUMBER APPEARS MORE FREQUENTLY THAN ANY OTHER NUMBER.
