Question

The median of 5,8,11,13,15,7,9 is *

Answer 1

Answer:

$\bold{Mean= \frac{sum \: of \: terms}{no \: of \: terms} }$

$\bold{Mean= \frac{5+8+11+13+15+7+9}{7} }$

$\bold{Mean= \frac{68}{7} }$

Therefore, Mean = 68/7

Answer 2

$5,8,11,13,15,7,9$

arranging in ascending order

$5,7,8,9,11,13,15$

$\: \: n = 7$

$\: \: \: \: \: \: \: \: median = ( \frac{n + 1}{2} )$

$\: \: \: \: \: \: \: \: \: median = \frac{7 + 1}{2}$

$\: \: \: \: \: \: m edian = 4 {}^{th} term$

$\: \: \: \: \: \: \: \: \: median = 9$
