Statistical Functions

Statistical calculations can be performed in STAT mode. The symbol will be visible if you are in STAT mode.

There are seven sub-modes within STAT mode, corresponding to each of the functions below:

Key operation	Sub-mode	Display
m10	SD: Single-variable statistics	Stat —
m11	LINE: Linear regression	Stat 1
m12	QUAD: Quadratic regression	Stat 2
m13	EXP: Exponential regression	Stat 3
m14	LOG: Logarithmic regression	Stat 4
m15	PWR: Power regression	Stat 5
m16	INV: Inverse regression	Stat 6

Entering statistical data

Before you can perform statistical calculations, you will need to enter your data. In STAT mode, use >and J(the Q key) to enter the following:

For a single-variable data set:

Value J

Value >frequency J(To enter multiples of the same value)

For a two-variable data set: x value >y value J

x value >y value >frequency J(To enter multiples of the same x and y values)

Note: Before entering data, clear any previously entered data from memory by doing either of the following:

•Press .bin STAT mode.

•Switch sub-modes within STAT mode.
