1. Press [MODE/SET UP][3].
2. Enter the function and press [=].
3. Enter the starting value, end value, step size, and press [=].
4. The table of values depends on every X input and is related to the output f(X).
Note: For this function, it is possible to use the X variable. The entered values
of the start, end and procedure should not exceed the number of 30 values of X.
Statistical calculations – STAT mode
Statistical calculations are used in the STAT mode, press [MODE/SET UP][2].
After you enter the statistical mode, there are 8 types of calculations to choose
from:
Statistics of one variable
1: 1-VAR Statistics of one variable.
Statistics of two variables
2: A+BX Linear regression
3: _+CX Quadratic regression
2
4: ln X Logarithmic regression
5: e^X Exponential regression
6: A•B^X Exponential regression
7: A•X^B Power regression
8: 1/X Inversion regression
Inserting data for statistical analysis
Before entering data, press [2ND][MODE/SET UP][▼][3] to switch on/off
the frequency table. The table enables you to enter numbers of repetitions for
every value.
In the STAT menu, select a calculation type. Data may be entered in two
formats (1-VAR or 2-VAR) that depend on the selection.
1. Enter the value of X and press [=].
2. Enter frequency (FREQ) of the occurrence of the value X (for the 1-VAR
mode) or corresponding value Y (for mode 2-VAR) and press [=].
3. To enter additional data, proceed according to step 3.
4. To end the data editor and display the results, press [AC] and then [2ND]
[⌐STAT¬] to display the ⌐STAT¬ menu.
Analysis of inserted data
After data are entered, there is a range of statistical functions to choose from by
pressing [2ND][⌐STAT¬]:
1: Type
2: Data
3: Sum
4: Var
5: Reg
6: MinMax
