Statistical Calculations (STAT)
To start a statistical calculation, perform the key operation

(STAT)
to enter the STAT Mode and then use the screen that appears to select the
type of calculation you want to perform.
To select this type of statistical calculation:
(Regression formula shown in parentheses)
Press this key:
Single-variable (X)

(1-VAR)
Paired-variable (X, Y), linear regression (
y
= A + B
x
)
2
(A+BX)
Paired-variable (X, Y), quadratic regression
(
y
= A + B
x
+ C

Paired-variable (X, Y), logarithmic regression
(
y
= A + Bln
