Here I found about Geometric median. But i am still unable to calculate Geometric median of some points (x, y). Can some body please calculate Geometric median by giving an example? For an example, let say i have six points a(-3,0), b(-2,0), c(-1,0), d(0,0), e(10,0), f(50,0). So what is the Geometric median of these points? Thank you.

What I do (crude but still helpful): Find median of data along X axis, find median of data along Y axis. This gives me coordination of "quite good estimatiom" of true geometric median. You can do the procedure to obtain means, however with simulations I found that using median is usually more correct.

I know this is very crude method, hope it helped you.
