Question

pls let me know the median of these numbers

Answer 1

Given data : 8,7,12,19,4,7,11
Ascending order : 4,7,7,8,11,12,19
No.of numbers in the given data n=7
Median=(n+1)/2
⇒(7+1)/2
⇒8/2
⇒4
Therefore,the fourth number in the data is 8 
So,8 is the median .

Answer 2

the given numbers are
8,7,12,19,4,7,11
the numbers arranged in increasing order.
4,7,7,8,11,12,19
the no.of observations (n)  = 7( odd)
then the mid term is is (n+1) /2
                                     = (7+1)/2 = 8/2 =4 th term
the 4th term = median
                   = 8
