Question

find the median of 18 19 20 23 22 20 17 19 25 21

Answer 1

Here's ur Answer:

After arranging these numbers in ascending order:17,18,19,19,20,20,21,22,23,25

N=10,

So,median=1/2(10/2 th term+10/2+1 th term)

=1/2(5th term+6th term)

=1/2(20+20)

=1/2*40

=20

Median =20

Answer 2

hey there

here ur answer

Simple definition of median:

             The middle number in the sets of numbers are termed as median.

Formula for finding median:

{(n + 1) ÷ 2}th

To find it:

18 19 20 23 22 20 17 19 25 21

In ascending order:

17,18,19,19,20,20,21,22,23,25

Here, there r two numbers so we wanna add it.

so, thn,

20 + 20

=40

=40/2

=20.

According to formula:

Here, there are 10 numbers in the set of number.

so n = 10

thn,

{(n + 1) ÷ 2}th

{(10 + 1) ÷ 2}th

{(11) ÷ 2}th

=5.5

(∵ Actually here, there r two numbers so, leave itas like that. here, we dont wanna to find / apply formula).

Hope this helps u
