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

= 6^{th} 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
