1) Mean = sum of all observation/ Total number of observation
Total Students = 15
Value of observation= 41, 39, 48, 52, 46, 62, 54, 40, 96, 52, 98, 40, 42, 52, 60
Mean =


Median:
1) Arrange data in ascending order
39,40,40,41,42,46,48,52,52,52,54,60,62,96,98
2) Total numbers of observation= 15
Odd: (n+1)/2
=(15+1)/2 = 8 th element is median
Median = 52
Mode:
1) Arrange data in ascending order
39,40,40,41,42,46,48,52,52,52,54,60,62,96,98
2) Count the frequency of each observation,the observation having most frequency is the mode
So, 52 appears 3 time,maximum time
Mode = 52
