The mean number of schools in each country is ( 5.43 ).

The median is the NUMBER AT THE CENTER of the data set.

Explanation:

To find the mean, you must add the number of schools then divide it by the amount of counties. 8+4+2+5+4+4+11= 38/7= 5.42 (you must round)

To find the median, you put the number of schools in order from least to greatest and find the number in the center.
