To find the median in a group of numbers, you need to arrange the numbers from least to greatest, and find the one in the middle. (It's pretty simple if you have an odd number of values, but if you have an even number of values, you can add the two in the center and divide them by 2.
The numbers you listed, when put in order from least to greatest, are:
11 13 15 18 20 20 22
If you look at it for a second, you'll see that the number in the center is 18. So, the median is 18.
First put them in numerical order,12, 13, 13, 15, 15, 18.since there is an even set of numbers the median is the mean of the two middle numbers12, 13, 13, 15, 15, 18.(13+15)/2=14
14, which is the middle number when they are listed in order.
15
sorted sample: 8 8 9 11 13 17 18 number of elements: 7 middle element and, therefore, the median: 11
16.5 is the median.
11 13 15 18 20 20 The median is the middle number when they are in numerical order, so the median is 16.5. It is 16.5 because there is an even number of integers so you find the middle of 15 and 18
The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.
It is 11.5
