Question

A data has 25 observations arranged in descending order. Which observation represents the median ?

Answer 1

$$\begin{gathered} \mathrm{Number}\mathrm{of}\mathrm{observations}=\mathrm{n}=25\left(\mathrm{odd}\right) \\ \mathrm{So},\mathrm{median}=\mathrm{value}\mathrm{of}{\left(\frac{\mathrm{n}+1}{2}\right)}^{\mathrm{th}}\mathrm{observation} \\ =\mathrm{value}\mathrm{of}{\left(\frac{25+1}{2}\right)}^{\mathrm{th}}\mathrm{observation} \\ =\mathrm{value}\mathrm{of}{13}^{\mathrm{th}}\mathrm{observation} \end{gathered}$$
