Order them: 15 16 17 21 21 Find the middle one: 17 That is the median

21. You put them in numerical order and then find the center one.

Median is finding the center of a line of some values. The values have to list in ascending order. When there are an odd amount of numbers: the median is the middle number. Example: find the Median of {12, 3, 5}. Put them in order: {3, 5, 12}. The middle number is 5, so the median is 5. When there are an even amount of numbers: There will be two numbers in the middle; the median in this case is the mean (average) of these two. Example: find the Median of {3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 40, 56}. There are now 14 numbers and so we have a pair of middle numbers and the middle numbers are 21 and 23. To find median: (21 + 23) ÷ 2 = 22. So the Median in this example is 22.

The median is 27.

The median is the number in the middle. First put the numbers in order:18, 21, 24, 37.Because there are an even number of numbers, there are two numbers in the middle: 21 and 24. The median is the average of these numbers : (21+24)/2 = 22.5.

You find the median to find the middle number

To find median: (21 + 23) ÷ 2 = 22. So the Median in this example is 22.

In order, the numbers are 18, 21, 24 and 37. Since there are an even number (4) of them, the median is the average of the middle two. ie median = (21+24)/2 = 22.5

The median is 27.
