To find the median, we first need to put the numbers in order from least to greatest: 0, 2, 9, 15, 19, 21, 39.
The median is the middle number, which is 15.
To find the mean, we add up all the numbers:
9 + 2 + 19 + 21 + 39 + 15 + 0 = 105
Then we divide by the total number of numbers in the set, which is 7:
105 รท 7 = 15
Therefore, the mean is also 15.
So, the median and the mean of the data set are both 15.
