Answer 1

Solution 1 :

First arrange data in ascending order

• 32,32,34,35,35,38,42

• Here Number of observation (n) = 7

$\sf => Median =\Bigg\lgroup\dfrac{n + 1}{ 2}\Bigg\rgroup^{th} \: observation$

$\sf => Median = \Bigg\lgroup\dfrac{7 + 1}{2}\Bigg\rgroup^{th} \: observation$

$\sf => Median = \bigg\lgroup\dfrac{8}{ 2}\bigg\rgroup^{th} \: observation$

$\sf => Median = 4^{th} \: observation$

$=> \underline{\boxed{ \sf Median = 35}}$

Solution 2 :

First arrange data in ascending order :

• 2,2,2,3,4,4,5,5,6,7,7,8,8

• Here Number of observation (n) = 13

$\sf => Median =\Bigg\lgroup\dfrac{n + 1}{ 2}\Bigg\rgroup^{th} \: observation$

$\sf => Median =\Bigg\lgroup\dfrac{13 + 1}{ 2}\Bigg\rgroup^{th} \: observation$

$\sf => Median =\bigg\lgroup\dfrac{14}{ 2}\bigg\rgroup^{th} \: observation$

$\sf => Median = 7^{th} \: observation$

$=> \underline{\boxed{ \sf Median = 5}}$
