Data Entry Hints
• Press
to enter the same data twice.
• Press
to enter the same data several times.
For example, pressing 30
40
5
enters the data pair {30, 40} 5 times.
• The some data entry hints noted for Standard
Deviation made (see earlier) also apply in
Regression mode.
• When carrying out statistical calculations, do not
store any data in variables A to F, X or Y. These
variables are used as temporary memory during
calculations and thus their contents could get
overwritten during a calculation.
• Variables A to F, X and Y are cleared when you
select REG mode and choose a regression type
(Lin, Log, Exp, Pwr, Inv, Quad). They are also
cleared if you switch to another regression type.
