dentify the first quartile in the following dataset:
5, 7, 9, 4, 3, 2, 1, 0, 11, 12, 6, 3, 4, 3, 2, 6(1 point)

The first quartile is the median of the lower half of the dataset.
First, we need to find the median of the entire dataset:
1, 2, 2, 3, 3, 3, 4, 4, 5, 6, 6, 7, 9, 11, 12
- The median is (6th + 7th) / 2 = (3 + 4) / 2 = 3.5
Now, for the first quartile, we need to find the median of the lower half of the dataset:
1, 2, 2, 3, 3
- The median of the lower half is (2nd + 3rd) / 2 = (2 + 2) / 2 = 2
Therefore, the first quartile is 2.
