Answer of this question

Hi Sameer,

To find Median, we follow the steps.

Suppose we have to find median of 2, 3, 4, 5, 0, 1, 3, 3, 4,

1. Arranging the numbers in ascending order
    0, 1, 2, 3, 3, 3, 3, 4, 4, 5
2. Find number of observations
   Number of observations = n = 10 (even number)
3. Since n is even
   Median = (n/2)th observation + (n/2 + 1)th observation /2
               = (10/2)th obs. + (10/2 + 1)th obs./2
               = (5𝑡ℎ 𝑜𝑏𝑠.+ 6𝑡ℎ 𝑜𝑏𝑠.)/2 = (3 + 3)/2 = 6/2 = 3
4. If n was odd, formula of median would be
   Median = (n + 1)/2 th observation (For example, check Ex 14.4, 2 of Class 9)
