Example
| Templex Expression | Results | 
|---|---|
{variance(6)} | 
                                0 | 
                            
{variance( {1, 2, 3, 4, 5} )} | 
                                2.5 | 
                            
{variance( { {1, 0}, {0, -1} } )} | 
                                0.666667 | 
                            
Comments
The following equation is used to calculate variance:

The result is always a scalar.
