To identify the first quartile (Q1) in a dataset, you need to follow these steps:
Step 1: Sort the dataset in ascending order.
The given dataset is: 5, 7, 9, 4, 3, 2, 1, 0, 11, 12, 6, 3, 4, 3, 2, 6
Sorting in ascending order: 0, 1, 2, 2, 3, 3, 3, 4, 4, 5, 6, 6, 7, 9, 11, 12
Step 2: Find the position of Q1.
The formula to find the position of Q1 is: (n + 1) / 4
n = number of data points, which is 16 in this case.
(16 + 1) / 4 = 4th position (since the result is not a whole number, round up to the nearest whole number)
Step 3: Identify the value at the position of Q1.
The value at the 4th position is 2.
Therefore, the first quartile (Q1) of the given dataset is 2.
So, the correct answer is 2.
