Question

Following are the lives in hours of $15$ pieces of the components of aircraft engine. Find the median.
$715,724,725,710,729,745,694,699,696,712,734,728,716,705,719$

Answer 1

Arrange the numbers in ascending order -

$694,696,699,705,710,712,715,716,79,724,725,728,729,734,745$

Total number of pieces $\left(n\right)=15$ (odd)

As we know that,

median = middle no. $\to$ (if $n$ = odd)

$\therefore$ median $=716$
