SCIENTIFIC CALCULATOR EL-509W EL-531W EL-531WG MODEL EL-531WH OPERATION MANUAL PRINTED IN CHINA / IMPRIMÉ EN CHINE / IMPRESO EN CHINA 04LGK (TINSE0706EH02) 2ndF HYP : Appears when @ is pressed, indicating that the functions shown in orange are enabled. : Indicates that h has been pressed and the hyperbolic functions are enabled. [. . . ] Conversion to each system is performed by the following keys: @ê: Converts to the binary system. " ", " ", " ", and " " disappear from the display. Conversion is performed on the displayed value when these keys are pressed. Note: In this calculator, the hexadecimal numbers A ­ F are entered by pressing TM, /, L, ÷, l, and I, and displayed as follows: F A B C D E Single-variable statistical calculation Statistics of Q Linear regression calculation Statistics of Q and W and, in addition, estimate of y for a given x (estimate y´) and estimate of x for a given y (estimate x´) Exponential regression, Logarithmic regression, Power regression, and Inverse regression calculation Statistics of Q and W. In addition, estimate of y for a given x and estimate of x for a given y. (Since the calculator converts each formula into a linear regression formula before actual calculation takes place, it obtains all statistics, except coefficients a and b, from converted data rather than entered data. ) Quadratic regression calculation Statistics of Q and W and coefficients a, b, c in the quadratic regression formula (y = a + bx + cx2). (For quadratic regression calculations, no correlation coefficient (r) can be obtained. ) When there are two x´ values, press @. When performing calculations using a, b and c, only one numeric value can be held. ¯ x sx x n x x 2 ¯ y sy y y y 2 xy r a b c Mean of samples (x data) Sample standard deviation (x data) Population standard deviation (x data) Number of samples Sum of samples (x data) Sum of squares of samples (x data) Mean of samples (y data) Sample standard deviation (y data) Population standard deviation (y data) Sum of samples (y data) Sum of squares of samples (y data) Sum of products of samples (x, y) Correlation coefficient Coefficient of regression equation Coefficient of regression equation Coefficient of quadratic regression equation Q A ï, B , C ó, D ò, E ô, F ö In the binary, pental, octal, and hexadecimal systems, fractional parts cannot be entered. When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. Likewise, when the result of a binary, pental, octal, or hexadecimal calculation includes a fractional part, the fractional part will be truncated. In the binary, pental, octal, and hexadecimal systems, negative numbers are displayed as a complement. W Time, Decimal and Sexagesimal Calculations Conversion between decimal and sexagesimal numbers can be performed. In addition, the four basic arithmetic operations and memory calculations can be carried out using the sexagesimal system. Notation for sexagesimal is as follows: · Use K and R to perform a STAT variable calculation. Data Entry and Correction Entered data are kept in memory until @c are pressed or mode selection. [Data Entry] Single-variable data Data k Data & frequency k (To enter multiples of the same data) Two-variable data Data x & Data y k Data x & Data y & frequency k (To enter multiples of the same data x and y. ) · Up to 100 data items can be entered. With the single-variable data, a data item without frequency assignment is counted as one data item, while an item assigned with frequency is stored as a set of two data items. With the two-variable data, a set of data items without frequency assignment is counted as two data items, while a set of items assigned with frequency is stored as a set of three data items. [Data Correction] Correction prior to pressing k immediately after a data entry: Delete incorrect data with ª, then enter the correct data. Correction after pressing k: Use [] to display the data previously entered. To reverse the display order to descending (latest first), press the [ key. Each item is displayed with `Xn=', `Yn=', or `Nn=' (n is the sequential number of the data set). Display the data item to modify, input the correct value, then press k.
