20
The median is 20, as it is the middle number when they are all listed in order.
In the example provided, the quartiles are: 25% = 16.5 (the median of {15, 16, 17, 18}) 50% = 18.5 (the median of {15, 16, 17, 18, 19, 20, 21, 22}) 75% = 20.5 (the median of (19, 20, 21, 22})

To find the mean, add all the numbers together (20 + 14 + 29 + 39 + 33 + 25 + 19 + 35 = 214) and divide by the total count (8), resulting in a mean of 26.75. The median is the middle value when the numbers are arranged in order (14, 19, 20, 25, 29, 33, 35, 39), which is the average of the two middle numbers (25 and 29), yielding a median of 27. The mode is the number that appears most frequently, and since all numbers in the list are unique, there is no mode.
