Answer 2

Hello,

Solution:

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

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

Hope it helps you.
