Accumulating Statistics
is a two-number function that calculates statistics of the
values in the X- and Y-registers. The results are automatically
accumulated in storage registers R, through Rs.

Any values remaining in Ry through Rg from previous
calculations or storage operations will be included in
subsequent statistics accumulations. To ensure that all
accumulations registers are set to zero before beginning a
new series of accumulations, press CLEAR [%](clears Rg
through Rg and the stack) before beginning the operation.
