To find the median of the numbers 12, 8, 5, 6, 1, 10, 13, and 11, we need to follow a few simple steps.
First, we start by arranging the numbers in ascending order:
1, 5, 6, 8, 10, 11, 12, 13
Next, we identify how many numbers are in the list. In this case, there are 8 numbers. When we have an even set of numbers, the median is found by taking the average of the two middle numbers.
In our ordered list, the two middle numbers are 8 and 10 (the 4th and 5th numbers). We calculate the median by adding these two numbers together and dividing by 2:
(8 + 10) / 2 = 18 / 2 = 9
Therefore, the median of the set of numbers is 9.
