Exploring the MEAN and MEDIAN -- This site helps you visualize what happens 
to the mean and median of a set of data when one of the numbers changes.  
There are four blue dots which represent 4 numbers.  These do not change.  
The red dot is the 5th number (the number that you get to change).  Watch 
carefully to see which landmark changes more easily as you drag the red dot 
back and forth.  Why do you think this happens?
