Question

The following table expresses the age of eight students. Find the median age.

Answer 1

This is an individual series, hence, So we need to arrange the data in the ascending order.

Here, the number of observations $=8$ (Even)

$\Rightarrow$ Median $=$ Average of $\frac{N}{2}$ observation and $(\frac{N}{2}+1)$ observation

$\Rightarrow$ Median $=$ Average of $\frac{8}{2}$ observation and $(\frac{8}{2}+1)$ observation

$\Rightarrow$ Median $=$ Average of $4$ th observation and $5$ th observation

$\Rightarrow$ Median $=$ $\frac{11+13}{2}$

$=$ $\frac{24}{2}$

$=12$

Therefore, Median $=12$ years
