Question

What is the median of..
9,25,18,15,6,16,8,22,21

Answer 1

Step-by-step explanation:

6 8 9 15 16 18 21 22 25

Total number of observations = 9

Median = (n+1)/2 term as the number of observations is odd

= (9+1)/2

= 5th term

=16

Answer 2

Given :

• 9, 25, 18, 15, 6, 16, 8, 22, 21.

ㅤㅤ

Find :

• What is the median?

ㅤㅤ

Concept :

• To solve this question we have to apply the "Median formula".

ㅤㅤ

• This concept is form the chapter of "Data handling".

ㅤㅤ

Applying formula :

★ Median = Sum of middle term/Total number of terms.

ㅤㅤ

Calculations :

→ 9, 25, 18, 15, 6, 16, 8, 22, 21.

ㅤㅤ

Therefore, 6 is the middle number and 6 is median.

Know more :

• Suppose if there are two numbers in the middle we must add the sun and divide with the number of middle terms and find the median in this way

Example :

→ 12(34)56

• Here, (3, 4) are to be used for finding media.

ㅤㅤ

→ Sum = 3 + 4 = 7

→ Total terms = 2

ㅤㅤ

→ Median = 7/2

→ Median = 3.5
