Answer:
The median is 13.
Step-by-step explanation:
The way you can find median is by putting the numbers in order from smallest to greatest, then finding the middle point. If the number of data points is odd, the median is the middle data point in the list. If the number of data points is even, the median is the average of the two middle data points in the list. Using this explanation, you can put your numbers in order.
8, 9, 11, 13, 14, 14, 15
As you can see, 13 is the middle number in the list.
