%4. Relevant Information: 						
%	This data set was generated to model psychological					
%	experimental results.  Each example is classified as having the					
%	balance scale tip to the right	 tip to the left	 or be		
%	balanced.  The attributes are the left weight	 the left			
%	distance	 the right weight	 and the right distance.  The		
%	correct way to find the class is the greater of 				
%	(left-distance * left-weight) and (right-distance *				
%	right-weight).  If they are equal	 it is balanced.			
%					
%5. Number of Instances: 625 (49 balanced	 288 left	 288 right)

%6. Number of Attributes: 4 (numeric) + class name = 5
