What is the median of this data set?

5 is the median of this data set.

Step-by-step explanation:

Median is the number in the middle. When the data is ordered from the least to the greatest (ascending order). If the two middle values, find the mean of two middle values.

Now we arrange this data in ascending order

2, 3, 3, 3, 4, 4, 5, 5, 5, 5, 5, 6, 7, 8, 8, 9, 9, 9, 10, 10

We find two numbers in the middle, we add them and divide with 2.

= (5 + 5) / 2

= 10 / 2 = 5

5 is the median of this data set.
