Answer:
median = 5.5
Explanation:
the median is the middle value of a data set arranged in ascending order
If there in exact middle value then it is the average of the values on either side of the ' middle '
arrange the data set into ascending order ( smallest to largest )
2 , 2 , 3 , 3 , 5 , 6 , 8 , 10 , 16 , 20
↑ middle is between 5 and 6
median = (5 + 6) ÷ 2 = 11 ÷ 2 = 5.5
