Question

find the median of the following observation. 72 ,68,42,33,39,40,41,65,69​

Answer 1

Step-by-step explanation:

68

92,35,67,85,72,81,56,51,42,69

No' of observations (n) =10

first of all we arrange the observations in an ascending order

35,42,51,56,67,69,72,81,85,92

Here observe that No' of observations (n) is even so

Median is average of

2

n

th term and (

n

+1) th term

Median =

+1)th term

=

5th term+6th term

=
