Answer:

The median of this data set is 1

Step-by-step explanation:

1) First sort the list of all the data set from the smallest to the largest

so we have (0,0,0,0,0,0,0,0,1,1,1,1,2,2,2,2,2,3,3,5,10)

2) Find the elements in the middle of the list

(0,0,0,0,0,0,0,0,1,1,1,1,2,2,2,2,2,3,3,5,10)

When you find an unique number your work is done, but when this happens the median is the average of the two elements in the middle of the sorted list

Hence the median is 1
