of display (X-register)
to zero
(page 21)

Statistics
z
Accumulates
numbers from X- and
Y-registers into storage
registers R
2
through R
7
(page 49)
.
w
Removes numbers
in X- and Y-registers
from storage registers
R
2
through R
7
for
correcting
z
accumulations
(page
52)
.
’
Computes mean of
x
- and
y
-values
accumulated by
z
(page 53)
.
S
Computes sample
standard deviations of
x
- and
y
-values
accumulated by
z
(page 53)
.
j
Linear estimate
and correlation
coefficient. Computes
estimated value of
y (ŷ)
for a given value of
x
by least squares method
and places result in X-
register. Computes the
correlation coefficient,
r,
of the accumulated
data and places result in
Y-register
(page 55)
.
L
Linear Regression.
Computes the
y
-
intercept and slope for
the linear function best
approximating the
accumulated data. The
value of the
y
-intercept
is placed in the X-
register; the value of the
slope is placed in the Y-
register
(page 54)
.
#
Random
number. Yields a
pseudorandom number
as generated from a
seed stored using
O
#
(page 48)
.
CLEAR
∑
Clears
contents of the statistics
registers (R
2
to R
7
)
(page 49)
.
Storage
O
Store. Stores a
copy of a number into
the storage register
specified {0 to 9, .0 to
.9,
V
,
%
}
(page
42)
. Also used for
storage register
arithmetic: new register
contents = old register
contents {
+
,
-
,
*
,
÷
} display
(page 44)
.
l
Recall. Recalls a
copy of the number
from the storage
register specified {0 to
9, .0 to .9,
V
,
%
}
(page 42)
. Also used
for storage register
arithmetic: new display
= old display {
+
,
-
*
,
÷
}
register contents
(page
44)
.
CLEAR
Q
Clears
contents of all storage
registers to zero
(page 43)
.
K
Recalls into
the display the number
present before the
previous operation
(page 35)
