Answer
Explanation:
Step1: Count the data - points
There are 3 data - points at 5, 1 at 6, 1 at 7, 1 at 8, and 1 at 10. So in total, there are $3 + 1+1+1+1=7$ data - points.
Step2: Find the position of the median
For a set of $n$ data - points, when $n$ is odd, the median is the $\left(\frac{n + 1}{2}\right)$-th ordered data - point. Here, $n = 7$, and $\frac{7+1}{2}=4$.
Step3: Order the data and find the median
Ordering the data (3 values of 5, 1 value of 6, 1 value of 7, 1 value of 8, 1 value of 10), the 4th value is 6.
Answer:
6
