The quartiles divide a dataset into four equal parts. In this case, we have 10 numbers, so the first quartile (Q1) would be the median of the first 5 numbers and the third quartile (Q3) would be the median of the last 5 numbers.
The first quartile (Q1) would be the median of 2, 4, 6, 8, and 10. The median of these values is 6.
The third quartile (Q3) would be the median of 12, 14, 16, 18, and 20. The median of these values is 16.
Therefore, the first and third quartiles are 6 and 16, respectively.
