Answer:
12,17,3,14,5,8,7,15
No' of observations (n) =8
first of all we arrange the observations in an ascending order
3,5,7,8,12,14,15,17
Here observe that No' of observations (n) is even so
Median is average of
2
n
th term and (
2
n
+1) th term
Median =

2
n
th term+(
2
n
+1)th term
=

8
th term+(

9,12,15,17,18,23,23,28,56,57,83
Ascending order= 9,12,15,17,18,23,23,28,56,57,83
Here no. of observations=11
Therefore the middle/central no.= median =23
