Question

2. Find the median of the following data.
23, 35, 18, 39, 42, 27, 40
​

Answer 1

Answer:

ARRANGE IN ASCENDING ORDER FIRST

18 , 23 , 27, 35, 39, 40 , 42

the no. of observations(n) = 7

The counting no . of observations is odd i.e; 7

therefore, median = (n+1) / 2 = (7 + 1) / 2 = 8/ 2 = 4

it means the fourth number is the median i.e; 35.

MEDIAN = 35

Answer 2

18,23,27,35,39,40,42 n=7 median=n/2th term + n/2+1 term, median=7/2 +7/2+1 median=3.5+4.5 median=8
