Answer
Explanation:
Step1: Arrange data in ascending order
1 2 2 3 4 5 6 6 7 7 7 8 8 8 8 9 9 9 9
Step2: Calculate position of Q3
There are $n = 19$ data - points. The position of $Q_3$ is $i=\frac{3(n + 1)}{4}=\frac{3\times(19 + 1)}{4}=\frac{3\times20}{4}=15$.
Step3: Find Q3
The 15 - th value in the ordered data - set is 8.
Answer:
8
