Median or middle

The number of hours of television watched per day by a sample of 28 people is given below:

4, 1, 5, 5, 2, 5, 4, 4, 2, 3, 6, 8, 3, 5, 2, 0, 3, 5, 9, 4, 5, 2, 1, 3, 4, 7, 2, 9

What is the median value?

Correct result:

m =  4 h

Solution:

$$\begin{gathered} 4,1,5,5,2,5,4,4,2,3,6,8,3,5,2,0,3,5,9,4,5,2,1,3,4,7,2,9 \\ s:0,1,1,2,2,2,2,2,3,3,3,3,4,4,4,4,4,5,5,5,5,5,5,6,7,8,9,9 \\ n=28 \\ {n}_2=n\mathrm{/}2=28\mathrm{/}2=14 \\ m=sorted[n_2] \\ m=4=4\text{ h} \end{gathered}$$
