(b). If statistical problem involves only one variable (x), clear storage
registers R.O through R.5 and Y-register.
Key number into X-register.
Press B .
NOTE
Unlike storage register arithmetic,
the accumulation operation allows over-
flows ( i.e., number whose magnitudes are greater than 9.99999999 x 10 99)
in storage registers R.O through R.5 without indicating Error 1 in the display.
(c).To use any of the accumulations,
recall contents of desired storage register
into displayed X-register by pressing
q q
followed by the number of the regis-
ter.
If this is done immediately after pressing H or ~- , the accumulation recal-
led is written over the number of data pair entries (n) in the display. To use both
~xand ~y
press I@ ~ .
This simultaneously copies ~x from R.1 into
displayed X-register and copies zy from R.3 into Y-register.
If this is done
immediately after pressing + ,~- , ~
or II@Q
, the number in the Y-
register is first lifted into the Z-register.
Otherwise, the numbers in the X- and
Y-registers are first lifted into Z- and T- registers, respectively.
Example:
To find ~x, ~xz, ~y, ~y2, and~xy for the paired values of x and
y listed below, press
