Answer 1

The dataset needs to be sorted in ascending order first:
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. In this case, the lower half is: 0, 1, 2, 2, 3, 3, 3, 4

Calculating the median of this lower half: (2 + 3) / 2 = 2.5

Therefore, the first quartile is 2.5.

Answer: 2.5
