STAT LIST (or STAT LIST

is
for
outputting
all
of
the statistics.
ST
AT
LIST I
is
for one-variable statistics alone and ST AT LIST 2 for paired-
variab
le
statistics.
The

Regression formula: y = a + b • x
EOX and EOY are treated as functions. These can be calculated in
the
same way
as
ordinary numerical functions;
"E
OXy
value"
or
"EOY x value".
Whenx
and
y values are variables
or
numeric values, parentheses can be
omitted
in the same
way
as
in
the
case
of
SIN, etc.
Now master statistical calculations
by
doing
the
following exercises:
Exercise:
The table

the
state
of
ship-
ments
of
product
x and product
y.
Deter-
mine
the
variance
of
shipments
by
finding
the standard deviation.
