Question

7. IF 10, 13, 15, 18, 2+1, 2-3, 30, 32, 35, 41 are ten observations in an
ascending order with median 24, find the value of x.​

Answer 1

answer

After arranging the given data in the ascending or descending order of magnitude, the value of the middle most observation, is called the median of the data.

Formula to find the median :)

Method : Arrange the data in increasing or decreasing order of magnitude. Let the total number of observation be n.

(i) If n is odd, then median

⇒ Value of \mathsf{( \frac{n + 1}{2} )\th}(

2

n+1

)th observation.

(ii) If n is even, then median

⇒ mean of \mathsf{( \frac{n}{2} )\th}(

2

n

)th and \mathsf{( \frac{n}{2} + 1 )\th}(

2

n

+1)th observations.
