Question

Find the median of the observations, 59, 75, 68, 70, 74, 75, 80.

Answer 1

The observations in ascending order: 59, 68, 70, 74, 75, 75, 80.

Since, the number of observation, n = 7, which is odd.

$\Rightarrow \mathrm{Median}=\left(\frac{n+1}{2}\right)\mathrm{th}=\left(\frac{7+1}{2}\right)\mathrm{th}=\left(\frac{8}{2}\right)\mathrm{th}=4\mathrm{th}\mathrm{Observation}=74$

So, the median of the observations is 74.
