Q23 of 33 Page 14

Find the mean, median and mode of the following data:







= 169


We have, N= 25,


N/2 = 12.5




Hence, median class =150-200, such that


l=150, F=6, f=10, h=50





= 170.83


Here, we may observe that maximum class frequency is 6 belonging to the class interval 150-200


So, modal class= 150-200


Lower limit, l= 150


f0=5, f2=5, f=6, h = 50






= 175


Hence mean is 169, median is 170.83 and mode is 175.
