Question

A data has 25 observations (arranged in descending order) which observations represents the median?

• A. ${13}^{th}$
• B. ${14}^{th}$
• C. ${15}^{th}$
• D. none of these

Answer 1

The correct option is A ${13}^{th}$

Number of observations =25

Number of observation are odd then

Median=value of ${\left(\frac{n+1}{2}\right)}^{th}$observation

$\Rightarrow \frac{25+1}{2}=\frac{26}{2}={13}^{th}$observation
