The StatBox is a little class which is designed to work a bit like the old fashioned pocket calculators in the statistical mode. One can reset the StatBox, one can put numbers in it, and find mean, standard deviation etc. The numbers themselves will not be stored in StatBox. So, correlations can't be calculated. But sometimes we are not interested in any more than means and variations. To calculate correlations, use CorrelationBox.
