How do you find the median of a data set?
To find the median of a data set, you must put the numbers in order from least to greatest and find the middle (center) number.
The following data set: 16, 14, 15, 18, 17, 20 and 25 can be organized into the following order: 14, 15, 16, 17, 18, 20, 25.
Now, simply find out the middle number.
17 is the middle number, therefore the median.
