Question

The median of the data 20,30,40,10,15,25,35 is?

Answer 1

$Given \:data : 20,30,40,10,15,25,35$

/* Arranging the data in ascending order,we get*/

$10,15,20,25,30,35,40$

$Number \: of \: terms (n) = 7 \: ( Odd )$

$Median =\Big( \frac{n+1}{2} \Big)^{th}\: term$

$= \Big( \frac{7+1}{2} \Big)^{th}\: term$

$= \Big( \frac{8}{2} \Big)^{th}\: term$

$= 4^{th} \:term$

$= 25$

Therefore.,

$\red{ Required \: median } \green {= 25 }$

Question :-

The median of the data 20,30,40,10,15,25,35 is?

Answer:-

Step-by-step explanation:

Given:-

Data is 20,30,40,10,15,25,35

To Prove:-

The median of the data mentioned above

Solution of the answer:-

Let make into accenting order we get

• 10,15,20,25,30,35,40

Nxt we need to find the median

The number of terms = 7 (oddl)

• To calculate the Median in an odd Sequence = (n+1)/2

• So, we get the answer ------->

7+1/2

=> 8/2

= 4th median of the given data

So the 4th term is 25

• The Median = 25
