Q11 of 33 Page 14

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




=62.4


We have, N= 50,


N/2 = 25


Hence, median class =60-80, such that


l=60, f’=12, f=24, h=20




=60+1.67


=61.67


Here, we may observe that maximum class frequency is 12 belonging to the class interval 60-80


So, modal class= 60-80


Lower limit, l= 60


f0=10, f2=6, f=12, h = 20



=
