The VARIANCE function returns a numeric value that approximates the variance of its arguments. The type of this function is
                  numeric. 
                  
 
            
            
               General Format
 
               	  
               	  
 
               
              
            
            
               Arguments
 
               	  
                
                  	 
                  - Argument-1 must be class numeric. 
                     	 
                  
  
            
            
               Returned Values
 
               	  
                
                  	 
                  - The returned value is the approximation of the variance of the argument-1 series. 
                     	 
                  
- The returned value is defined as the square of the standard deviation of the argument-1 series. (See the topic 
                     		The STANDARD-DEVIATION Function.) 
                     	 
                  
- If the argument-1 series consists of only one value, or if the argument-1 series consists of all variable occurrence data
                     items and the total number of occurrences for all of them is one, the returned value is zero. 
                     	 
                  
- Floating-point format is used for numeric non-integer results.
