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 (SD): Single-variable statistics
1 (a+bx): Linear regression
2 (a+bx+cx
): Quadratic regression
2
⋅
3 (a
e^bx): Euler exponential regression
⋅
4 (a+b
lnx): Logarithmic regression
⋅
5 (a
x^b): Power regression
6 (a+b/x): Inverse regression
⋅
7 (a
b^x): General exponential regression
The statistical data input screen appears.
After entering statistical data from the input screen, press _ or j
and close the input table. You can then check statistical values from the
STAT menu (; 8) and specify statistical variables.
Data Entry and Correction

• After entering the data, press e. The input is finalized and the
cursor moves to the next line. If data was not entered in an
entered, 1 is entered in FRQ (frequency), and the cursor moves to the
next line.
• You can use H to enter X and FRQ (or X, Y, and FRQ) at once.
• In the input table, up to 6 digits are displayed for each value,
including the sign and decimal point. Any values that exceed 6 digits
in length are displayed in exponent notation.
• Up to 100 data items can be entered. With single-variable data,
a data item with an assigned frequency of one is counted as one
data item, while an item with an assigned frequency of 2 or higher
is stored as a set of two data items. With two-variable data, a set of
data items with an assigned frequency of one is counted as two data
items, while a set of items with an assigned frequency of 2 or higher
is stored as a set of three data items.
• To execute statistical calculation, press _ or j and close the
input table.
Data correction
Use l, r, u, or d to move the cursor and select the
desired data. Press @ u or @ d to jump the cursor to the
beginning or end of the data.
Data correction
Move the cursor to the data that you want to correct, enter the numeric
value, and press e.
Data insertion
To insert a line in front of the cursor position, press ; T.
The initial values entered in the inserted data are 0 in x and y, and 1
in FRQ.
Data deletion
To delete the entire line where cursor is positioned, press @ y.
Notes:
• In STAT mode, all statistical data will be erased if the submode is
changed or @ Z is pressed.
• In STAT mode, press _ to display the input table.

Normal Probability Calculations
In STAT mode, the three probability density functions can be accessed
under the MATH menu, with a random number used as a normal
distribution variable.
Notes:
• P(t), Q(t), and R(t) will always take positive values, even when t < 0,
because these functions follow the same principle used when solving
for an area.
• Values for P(t), Q(t), and R(t) are given to six decimal places.

Notes on erasure of memory contents
When the battery is replaced, the memory contents are erased.
Erasure can also occur if the calculator is defective or when it is
repaired. Make a note of all important memory contents in case
accidental erasure occurs.
When to Replace the Battery
If the display has poor contrast or nothing appears on the display when
j is pressed in dim lighting, even after adjusting the display contrast,
it is time to replace the battery.
Cautions
• An exhausted battery left in the calculator may leak and damage the
calculator.
• Fluid from a leaking battery accidentally entering an eye could
result in serious injury. Should this occur, wash with clean water and
immediately consult a doctor.
• Should fluid from a leaking battery come in contact with your skin or
clothes, immediately wash with clean water.
• If the product is not to be used for some time, to avoid damage to the
unit from a leaking battery, remove it and store in a safe place.
• Do not leave an exhausted battery inside the product.
• Keep batteries out of the reach of children.
• Explosion risk may be caused by incorrect handling.
• Do not throw batteries into a fire as they may explode.
Replacement Procedure
1. Turn the power off by pressing @ o.
2. Remove two screws. (Fig. 1)
3. Lift the battery cover to remove.
4. Remove the used battery by prying it out with

Using Vectors in Calculations
vectors stored in memories (vectA–vectD) can be used in arithmetic
calculations (with the exception of division between vectors). You can

Notes:
• You can use "abs" function (abs vector name) for the absolute value.
• When multiplying vectors, the cross product is calculated.
• When the vector entry screen is displayed, press j and then you
