To find the first quartile in a dataset, you need to arrange the numbers in ascending order. Here is the dataset arranged in ascending order:
0, 1, 2, 2, 3, 3, 3, 4, 4, 5, 6, 6, 7, 9, 11, 12
The first quartile (Q1) is the median of the lower half of the dataset. Since there are 16 numbers in the dataset, the lower half consists of the first 8 numbers:
0, 1, 2, 2, 3, 3, 3, 4
The median of this lower half is the number in the middle, which is 3. Therefore, the first quartile (Q1) for this dataset is 3.
