What is the median of several numbers?

From a statistics book open in front of me, I read

The median of a set of data is the data point in the middle of the 
list (arranged in order) if the list has an odd number of entries and 
is the average of the two in the middle if the list has an even number 
of entries.

For example, here are some weights of persons:

  98, 104, 110, 118, 125, 140, 175

The median is 118 since it is the middle point.  If the weights were

  98, 104, 110, 118, 125, 140, 175, 201

then the median would be (118+125)/2 = 121.5.
