Question

A student scored the following marks in 11 questions paper : 7,3,4,1,5,8,2,2,5,7,6. Find the mediam marks​

Answer 1

A student scored the following marks in 11 questions paper :

• 7, 3, 4, 1, 5, 8, 2, 2, 5, 7, 6

Arrange the data in ascending order, we have

• 1, 2, 2, 3, 4, 5, 5, 6, 7 7, 8

Here, number of observations,

• n = 11 (odd).

So, median of the above data is given by

$\bigstar \: \: { \boxed{ \red{ \tt \: median \: = \: {(\dfrac{n + 1}{2} )}^{th} \: observation}}}$

So,

$\rm :\implies\:median \: = \: {(\dfrac{11 + 1}{2} )}^{th} \: observation$

$\rm :\implies\:median \: = \: {(\dfrac{12}{2} )}^{th} \: observation$

$\rm :\implies\:median \: = \: {(6 )}^{th} \: observation$

$\bigstar \: \: { \large\boxed{ \pink{ \tt \: median \: = \: 5}}}$

Answer 2

Answer:

1,2,2,3,4,5,5,6,7,7,8. then there are total 11 numbers which is odd. so the median is the middle numbers which is =5
