| Statistical Operators |
Factorial
Calculates the factorial of a number or expression. Valid parameter range: 0 - 9,999, allows decimal or complex arguments.
▸ Example: Factorial of 5:
5 ¶ = ➜ 5×4×3×2×1 ➜ 120
| Statistical Functions |
Permutation (nPr)
Calculates the number of different possible orderings in selecting r objects from a set of n objects
r - the value on the right side of the function
n - the value on the left side of the function
▸ Calculate 10 Pr 4
1 0 P 4 = ➜ 5040
Combination (nCr)
Calculates the number of ways of selecting r objects from a set of n objects
r - the value on the right side of the function
n - the value on the left side of the function
▸ Calculate 10 Cr 4
1 0 Q 4 = ➜ 210
Random Number
Generates a random number between 0 and a selected parameter. Works also with negative values.
▸ Generate a number between 0 to 100
Y 1 0 0 = ➜ 72.448246406...
▸ Generate an integer number between 0 to 10
ȹ Y 1 0 = ➜ 7
| Statistical Dialog Box |
The statistical dialog box facilitates numerous statistical calculations based on a list of values (stack). These values are saved and managed within the dialog, which is organized into two tabs:
STACK - List of values inserted by the user for statistical calculations.
CALC - List of statistical functions and their results, calculated according to stack values.
➤ Note: The stack size is limited to 999 items.
Operations on Results:
| USE | Enters the selected result into the calculator display. |
| PRM | Stores the selected value in a parameter. Opens a parameter selection dialog box. |
| Ț | Copies the selected result to the clipboard. |
| MS | Stores the selected result in the calculator memory. |
