Question

The median of thr data 11,29,17,21,13,31,39,19 is

Answer 1

Answer:

the numbers are even so there is no median

Step-by-step explanation:

if we take 3 and 3 there will be 21,13

so,

21+13/2

34/2

=17

Answer 2

Median of data 11,29,17,21,13,31,39,19 is 20.

Given:

11,29,17,21,13,31,39,19

To find: The median of given data.

Solution:

Formulas to be used:

1. Median of even numbers: Mean of (n/2)th and (n/2+1)th data.
2. Mean= Sum of all observation/Total observation

Step 1:

Count the numbers.

Total given numbers are 8.

Thus,

n=8

Step 2:

Arrange the number in ascending order.

11, 13, 17, 19, 21, 29, 31, 39

Step 3:

Find (n/2)th and (n/2+1)th data

(n/2)th= (8/2)th = 4th

4th data is 19

(n/2+1)th =(4+1)th= 5th

5th data is 21

Step 4:

Find Mean of 19 and 21.

$= \frac{19 + 21}{2}$

$= \frac{40}{2}$

$= 20$

Thus,

Median of given data is 20.
