There are 9 data - points. The median is the 5th value, so $Q_2 = 11$.

Step5: Find the lower half

The lower half of the data is $1,3,6,9$.

Step6: Find $Q_1$

The median of the lower half is $\frac{3 + 6}{2}=4.5$.

Step7: Find the upper half

Step8: Find $Q_3$

The median of the upper half is $\frac{13+17}{2}=15$.
