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?

Result

m =  4 h

Solution:

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 n2=n/2=28/2=14 m=sorted[n2] m=4 h4, 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/2=28/2=14 \ \\ m=sorted[n_{2}] \ \\ m=4 \ \text{h}



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
