Answer :
The median of a set of numbers is the quantity that separates the higher half from the lower half of a data set.
To find it, list the numbers from smallest to greatest:
[tex]50,53,55,56,67,70,71,83,88[/tex]There are 9 numbers in total. Since there are 4 numbers before and after the 5th number, then the median is the number in the 5th place, which is 67.
Therefore, the median score is 67.
