Solution Steps

Step 1: Sort the Dataset

The sorted dataset is: [0, 0, 0, 0, 1, 1, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6, 6, 6, 7, 7, 7, 8, 8, 8, 8, 9, 9, 9].

Step 2: Calculate the Position of Quartiles

The position for Q1 is calculated using the formula: $\frac{1}{4}(n+1) = 7.25$. The position for Q2 (Median) is calculated using the formula: $\frac{1}{2}(n+1) = 14.5$. The position for Q3 is calculated using the formula: $\frac{3}{4}(n+1) = 21.75$.

Step 3: Extract Quartiles

Q1 (First Quartile) is found at position 7.25: 2. Q2 (Second Quartile or Median) is found at position 14.5: 4.5. Q3 (Third Quartile) is found at position 21.75: 7.75.

Final Answer:

The first quartile (Q1) is 2, the second quartile (Q2) or median is 4.5, and the third quartile (Q3) is 7.75.
