STATISTICAL CALCULATIONS
Statistical calculations can be performed in STAT mode.
There are eight sub-modes within STAT mode. Press
b
1
, then press the number key that corresponds to your
choice:
0
(S#a# 0 [SD]): Single-variable statistics
1
(S#a# 1 [LINE]): Linear regression
2
(S#a# 2 [QUAD]): Quadratic regression
3
(S#a# 3 [E_EXP]): Euler exponential regression
4
(S#a# 4 [LOG]): Logarithmic regression
5
(S#a# 5 [POWER]): Power regression
6
(S#a# 6 [INV]): Inverse regression
7
(S#a# 7 [G_EXP]): General exponential regression
Statistical Calculations and Variables
The following statistics can be obtained for each
statistical calculation (refer to the table below):
Single-variable statistical calculation
Statistics of ① and the value of the normal probability
function.
Linear regression calculation
Statistics of ① and ②. In addition, the estimate of
y for a
given
x (estimate y´) and the estimate of x for a given y
(estimate
x´).
