Note: For some reason completely beyond me Google Sites does not allow applets anymore. I relocated the applet and copied the page here -

The Geometric Median
A Java applet demonstrating the Geometric Median vis-a-vis Centroid

The blue point is the Centroid. The red point is the Geometric Median. Initially there are 5 points put randomly on the plane, but you may use the mouse to alter point configuration.

  • To move a point, click and drag
  • To add a point, click in empty space
  • To delete a point, right click
