Answer 2

The median of the runs scored by 11 players = 30

Given :

The number of runs scored by 11 players of a cricket team of a school is 5 , 19 , 42 , 11 , 50 , 30 , 21 , 0 , 52 , 36 , 77

To find :

The median of the runs scored by 11 players

Concept :

Median

Median is the middle most value of a set of observations when the samples are arranged in order of magnitudes ( Either in ascending or in descending)

Solution :

Step 1 of 3 :

Write down the runs scored by 11 players

Here it is given that the the number of runs scored by 11 players of a cricket team of a school is 5 , 19 , 42 , 11 , 50 , 30 , 21 , 0 , 52 , 36 , 77

Step 2 of 3 :

Rearrange in ascending order

Rearranging the runs scored by 11 players in ascending order we get

0 , 5 , 11 , 19 , 21 , 30 , 36 , 42 , 50 , 52 , 77.

Step 3 of 3 :

Find the median

Number of observations = 11 which is odd

Therefore the required median

= The middle term of the whole arranged observations

$\displaystyle \sf{ = \frac{11 + 1}{2} \: th \: observation }$

$\displaystyle \sf{ = \frac{12}{2} \: th \: observation }$

$\displaystyle \sf{ = 6 \: th \: observation }$

= 30
