To find the first quartile (Q1) of the dataset, we first need to arrange the data in ascending order:
0, 2, 3, 4, 5, 7, 8
The first quartile (Q1) is the median of the first half of the data. In a dataset of 7 numbers, the first half consists of the first three numbers:
0, 2, 3
The median of this subset (for Q1) is the second number:
Q1 = 2
So the correct response is 2.
