find the mean , mode, range , mediam for the following set of data
16 , 40 , 44 , 16 ,40 , 40 , 80 , 17 , 64 , 64 , 100
Arrange these numbers in ascending order
16,16,17,40,40,40,44,64,64,80,100
Mean =
=
=
= 47.36
Here , we have total 11 numbers of observation so,
Median = ]th term
= 12/2 th term
= 6th term
= 40
Range = largest term – smallest term
= 100 – 16
= 84
Mode = the observation which is occurred maximum number of time
So, it is 40 which is occurred most number of times i.e. 3
Hence mode = 40
