You can change the function of a key by pressing another key first, or by setting the calculator in a certain mode. [. . . ] The program you just entered is stored in the program memory. PGM disappears and the calculator exits the program mode. [ RUN ] Compute Key Specify Variable Key Temporarily Halt Calculation Key Runs the recorded program. [ 2ndF ] [ [x] ] Lets you have the calculator wait for an entry during a program. [ 2ndF ] [ HALT ] Temporarily halts a program so you can view the intermediate results or interrupt calculation. STATISTICAL KEYS (USE IN THE STAT MODE ONLY) [ 2ndF ] [ STAT ] Statistical Mode Select Key Sets the calculator to statistical calculation mode. [ 2ndF ] [ CAD ] Statistical Register Clear Key Clears the statistical calculation registers. -E6- [ DATA ], [ DEL ] Data Entry and Delete Key In the STAT mode, enter data by pressing the desired numbers, then [ DATA ]. If you enter incorrect data and do not notice your mistake until you press [ DATA ], enter the same incorrect data and then press [ DEL ] to delete that incorrect data. [ x ] Arithmetic Mean Key Calculates the arithmetic mean ( x ) of the data. [ 2ndF ] [ ] Population Standard Deviation Key Calculates the population standard deviation of the data. [ s ] Sample Standard Deviation Key Calculates the sample standard deviation of the data. [ 2ndF ] [ [ 2ndF ] [ x 2 ] Sum of Square Value Key x 2) of the data. x ] Sum of Value Key Calculates the sum of the square value ( Calculates the sum of the value ( x ) of the data. [ n ] Number of Data Key Displays the number of data (n) entries. The Display Indicators showed on the display to indicate you the current status of the calculator. · Floating point displays up to 10 digits. · The mantissa section displays up to 8 digits. STAT M ­ E PGM CONST GRAD RAD DEG BUSY : Indicates the statistical mode. : Indicates that a value is stored in memory. : Appears to the left of the mantissa or exponent to indicate that the respective value is negative. : Indicates the gradient units have been selected. : Indicates that radian units have been selected. : indicates that degree units have been selected. [. . . ] You can have more than one variable in your calculation. Your calculator learns mathermatical procedures or programs in the program (PGM) mode. To set the calculator to the program mode, press [ 2ndF ] [ PGM ]. Now enter your procedure as if you were just going to calcualte it once except press [ 2ndF ] [ [x] ] before entering variable data.
