Answer:
Here are your numbers arranged in ascending order:
-15, -13, -12, -10, -8, -6, -5, 0
There are 8 numbers in the list, which is an even number. So, you need to find the average of the two middle values, which are the fourth and fifth values:
Median = (-10 - 8) / 2 = (-18) / 2 = -9
So, the median of the given numbers is -9.
