Solution

Finding median of the given data:
Given data, $5, 7, 8, 9, 11, 13, 15$
Here, number of terms $(n) = 7$
So, $M e d i a n = \frac{n + 1}{2} t h t e r m f o r o d d n u m b e r o f t e r m s .$
Hence, Median $= \frac{7 + 1}{2} = 4^{t h} t e r m$
In the given data, $4^{t h}$ term is $9$ .
Hence, median of the given data is $9$ .
