STATISTICAL CALCULATIONS [SD] [REG]
To enter the standard deviation mode by pressing
, [SD] indicator lights up. If press , you can
enter the regression mode selection menu. [REG]
indicator will be turned on.
Before starting, be sure to clear the statistic memory by
pressing .
Perform the data input (Precautions!).

pressing will input the same data twice.
• In REG mode, store the x-data and y-data in the form
of:
x-data y-data , pressing will input the
same data twice.
• Use for same data multiple entries.
For example in SD mode, the data 20 has 8 times will
press 20 8 .
• Press or key during or after data input can display
the data value (x) and data frequency (Freq). Follow
with the above example, press will display [x1 = 20],
and press will display [Freq1= 8].
• To edit the stored data, input the new value during the
display of that data value (x) after pressing or key,
and then press to confirm the edit. But, if you
press instead of , a new data value will be
