Answer

Answer:

8

Explanation:

Step1: Count data - points

There are 1 + 1+ 2 + 1+ 5+ 1 = 11 data - points.

Step2: Determine position of median

For a set of (n = 11) data - points, the median is the (\left(\frac{n + 1}{2}\right))-th value. (\frac{11+ 1}{2}=6) - th value.

Step3: Arrange data and find median

Arrange the number of letters in ascending order: 5, 6, 7, 7, 8, 9, 9, 9, 9, 9, 10. The 6 - th value is 8.
