Question

calculate the value of median from the following figures
Roll no.
variable - 18, 22, 30, 40, 50, 56, 32, 36, 34, 16, 22​

Answer 1

as the number of observations are odd so show the formula used is(n+1)/2

Step-by-step explanation:

first arrange the number in ascending or descending order.

like: 16 18 22 22 30 32 34 36 40 50 56

then use the formula...

number of observations equal to 11

so, median= 11+1/2

12/2 = 6th observation

so 6th observation is 32

median =32

Answer 2

The value of median from the following figures of roll numbers is 32.

Step-by-step explanation:

Median : It is the middle term that is sorted by the list of numbers. It is determine by placing the numbers in increasing order.

Arrange the data in increasing order :

16, 18, 22 , 22, 30, 32 , 34 , 40, 50 ,56

n = 11

For odd observations the formula will be: $\frac{n+1}{2}$

$Median=\frac{11+1}{2}=6$

6th term = 32

The value of median from the following figures of roll numbers is 32.
