Question

find the median of the following dates-: 15,13,10,9,14, 18, 20, 21, 22,​

Answer 1

Answer:

Data in ascending order

9,10,13,14,15,18,20,21,22

We notice that n=9 which is odd

$Median= \frac{n + 1}{2}th$

$Median= \frac{9 + 1}{2}th$

$Median= \frac{10}{2}th$

Median=5th observation

Median=14

Answer 2

15 , 13 , 10 , 9 , 14 , 18 , 20 , 21 , 22

Put them in order

9 , 10 , 13 , 14 , 15 , 18 , 20 , 21 , 22

So the middle term is 15

Median = n+1 / 2 th

9+1 / 2

10 / 2

So median is 14
