Answer:
10.5
Step-by-step explanation:
6, 7,8, 9,10, 11, 12, 15, 16, 17
10+11= 21
21÷2= 10.5
When there is an even number of values in a set of data, there is no single middle value. That makes it a little more difficult to find the median. In his case, you take the two middle values and add them together. Then you divide the sum by of the values by 2. This gives you the median.
