Chapter 2 Manual Calculations 1. Basic Calculations k Arithmetic Calculations • Enter arithmetic calculations as they are written, from left to right. • Use the - key to input the minus sign before a negative value. • Calculations are performed internally with a 15-digit mantissa. The result is rounded to a 10digit mantissa before it is displayed. • For mixed arithmetic calculations, multiplication and division are given priority over addition and subtraction. Example Operation 56 × (–12) ÷ (–2.5) = 268.
Example 1 100 ÷ 6 = 16.66666666... Condition Operation Display 100/6w 16.66666667 4 decimal places !m(SET UP) ff 1(Fix)ewJw *1 16.6667 5 significant digits !m(SET UP) ff 2(Sci)fwJw *1×1001 1.6667 Cancels specification !m(SET UP) ff 3(Norm)Jw 16.66666667 *1 Displayed values are rounded off to the place you specify. Example 2 200 ÷ 7 × 14 = 400 Condition Operation 3 decimal places Display 200/7*14w 400 !m(SET UP) ff 1(Fix)dwJw 400.
k Calculation Priority Sequence This calculator employs true algebraic logic to calculate the parts of a formula in the following order: 1 Type A functions • Coordinate transformation Pol (x, y), Rec (r, θ) • Functions that include parentheses (such as derivatives, integrations, Σ, etc.
Example 2 + 3 × (log sin2π2 + 6.8) = 22.07101691 (angle unit = Rad) 1 2 3 4 5 6 • When functions with the same priority are used in series, execution is performed from right to left. exln 120 → ex{ln( 120)} Otherwise, execution is from left to right. • Compound functions are executed from right to left. • Anything contained within parentheses receives highest priority.
Since the calculation result uses a common denominator, calculation result still may be displayed using the ' format even when coefficients (a´, c´, d´) are outside the corresponding range of coefficients (a, c, d). Example: 3 + 11' 2 3 ' 2 10' ' + = 110 11 10 Calculation Examples This calculation: Produces this type of display: 2 × (3 – 2' 5) = 6 – 4' 5 ' format 35' 2 × 3 = 148.492424 (= 105 ' 2)*1 Decimal format 150' 2 = 8.485281374*1 25 23 × (5 – 2' 3) = 35.
Calculation Examples This calculation: Produces this type of display: 78π × 2 = 156π π format 123456π × 9 = 3490636.164 (= 11111104 π)*3 Decimal format 105 2 568 71 π = 105 π 824 103 π format 258 π = 6.533503684 3238 2 129 π *4 1619 Decimal format *3 Decimal format because calculation result integer part is |106| or greater. *4 Decimal format because number of denominator digits is four or greater for the a b π form.
If you execute a calculation in which a multiplication sign has been omitted immediately before a fraction (including mixed fractions), parentheses will be inserted automatically as shown in the examples below. 1 1 ): 2 3 3 Example (2 × Example (sin 2 × → 2 4 4 ): sin 2 5 5 ( 13 ) → sin 2 ( 45 ) k Overflow and Errors Exceeding a specified input or calculation range, or attempting an illegal input causes an error message to appear on the display.

Chapter 6 Statistical Graphs and Calculations Important! This chapter contains a number of graph screen shots. In each case, new data values were input in order to highlight the particular characteristics of the graph being drawn. Note that when you try to draw a similar graph, the unit uses data values that you have input using the List function. Because of this, the graphs that appear on the screen when you perform a graphing operation will probably differ somewhat from those shown in this manual. 1.
k General Graph Settings [GRAPH]-[SET] This section describes how to use the general graph settings screen to make the following settings for each graph (GRAPH1, GRAPH2, GRAPH3). • Graph Type The initial default graph type setting for all the graphs is scatter graph. You can select one of a variety of other statistical graph types for each graph. • XList, YList The initial default statistical data is List 1 for single-variable data, and List 1 and List 2 for paired-variable data.
u To display the general graph settings screen Pressing 1(GRAPH)6(SET) displays the general graph settings screen. • StatGraph (statistical graph specification) • {GRAPH1}/{GRAPH2}/{GRAPH3} ... graph {1}/{2}/{3} • Graph Type (graph type specification) • {Scatter}/{xyLine}/{NPPlot}/{Pie} ... {scatter diagram}/{xy line graph}/{normal probability plot}/{pie chart} • {Hist}/{MedBox}/{Bar}/{N-Dist}/{Broken} ...
For this graph type: Selecting this: Causes this to happen: NPPlot, Pie, Bar On The color specified for the list data is reflected in the graph. Off List data color specifications are ignored. Hist, Broken X&Freq Colors specified for both the XList and Frequency data list are reflected in the graph. • When the same lines of the XList and Frequency data list are the same color, the graph is drawn using that color.
• {Auto} ... Cycles the color used for graph drawing in the following sequence for each data item (or data pair): blue, red, green, magenta, black. Cycle is repeated after all five colors are used. For some graphs, different parts of the graph (points, lines, etc.) are automatically drawn using different colors. {Auto} can be selected only when the graph type is Scatter, xyLine, NPPlot, or Broken.
When “Hist” (Histogram) is selected as the Graph Type: • Hist Area (Specifies the fill color of a histogram.) Settings are the same as those for Pie Area. • Hist Border (Specifies the border line color of a histogram.) Settings are the same as those for Pie Border. • The Hist Border setting is always “Link” whenever anything other than “Off” is selected for the Color Link setting. When “MedBox” (med-box graph) is selected as the Graph Type: • Outliers (outliers specification) • {On}/{Off} ...
• D1 Area, D2 Area, D3 Area (Specifies the fill colors of bar graphs Data 1, Data 2, and Data 3.) Settings are the same as those for Hist Area. • D1 Border, D2 Border, D3 Border (Specifies the border colors of bar graphs Data 1, Data 2, and Data 3.) Settings are the same as those for Hist Border. k Graph Draw/Non-draw Status [GRAPH]-[SELECT] The following procedure can be used to specify the draw (On)/non-draw (Off) status of each of the graphs in the graph menu.
2. Calculating and Graphing Single-Variable Statistical Data Single-variable data is data with only a single variable. If you are calculating the average height of the members of a class for example, there is only one variable (height). Single-variable statistics include distribution and sum. The following types of graphs are available for single-variable statistics. You can also use the procedures under “Statistical Graph Parameters” on page 6-1 to make the settings you want before drawing each graph.
k Histogram XList specifies the list where the data is input, while Freq specifies the list where the data frequency is input. 1 is specified for Freq when frequency is not specified. ⇒ w(Draw) The display screen appears as shown above before the graph is drawn. At this point, you can change the Start and Width values. k Med-box Graph This type of graph lets you see how a large number of data items are grouped within specific ranges.
k Bar Graph You can specify up to three lists for drawing a bar graph. The graph is labeled [1], [2], [3], and so on, corresponding to lines 1, 2, 3, and so on of the list used for the graph data. • Any of the following causes an error and cancels bar graph drawing. - A Condition ERROR occurs when drawing of multiple graphs is specified using the graph On/Off screen (page 6-7), and bar graph is specified for one of the graphs and a different graph type is specified for another graph.
⇒ w(Draw) The display screen appears as shown above before the graph is drawn. At this point, you can change the Start and Width values. k Displaying the Calculation Results of a Drawn Single-Variable Graph Single-variable statistics can be expressed as both graphs and parameter values. When these graphs are displayed, the single-variable calculation results appear as shown to the right when you press 1(1-VAR). • Use c to scroll the list so you can view the items that run off the bottom of the screen.
k Calculation Methods for the Std and OnData Settings Q1, Q3 and Med can be calculated in accordance with the Setup screen’s “Q1Q3 Type” setting as described below. u Std (1) When all Frequency values are integers With this calculation method, processing depends on whether the number of elements n in the population is an even number or odd number.
Center Point 1 2 3 Center Point 4 5 6 7 8 9 Median 2+3 = Q1 2 7+8 = Q3 2 (2) When Frequency includes decimal fraction values The Q1, Q3 and Med values for this calculation method are described below. Q1 = {value of element whose cumulative frequency ratio is greater than 0.25 and nearest to 0.25} When the cumulative frequency ratio for some data value is exactly 0.25, Q1 is the average of that data value and the next data value.
u OnData The Q1, Q3 and Med values for this calculation method are described below. Q1 = {value of element whose cumulative frequency ratio is greater than 0.25 and nearest to 0.25} Q3 = {value of element whose cumulative frequency ratio is greater than 0.75 and nearest to 0.75} The following shows an actual example of the above. (Number of Elements: 10) Data Value Frequency Cumulative Frequency Cumulative Frequency Ratio 1 1 1 1/10 = 0.1 2 1 2 2/10 = 0.2 3 2 4 4/10 = 0.4 4 3 7 7/10 = 0.

The regression formula parameter calculation results also appear as soon as you press 1(CALC) and then a function key to select a regression type, while a graph is on the display. The following parameters will also appear on the regression calculation result screen. r ..............
k Med-Med Graph When it is suspected that there are a number of extreme values, a Med-Med graph can be used in place of the least squares method. This is similar to linear regression, but it minimizes the effects of extreme values. 1(CALC)3(Med) 6(DRAW) The following is the Med-Med graph model formula. y = ax + b a .............. Med-Med graph slope b ..............
k Logarithmic Regression Graph Logarithmic regression expresses y as a logarithmic function of x. The standard logarithmic regression formula is y = a + b × ln x, so if we say that X = ln x, the formula corresponds to linear regression formula y = a + bX. 1(CALC)6(g)2(Log) 6(DRAW) The following is the logarithmic regression model formula. y = a + b·ln x a .............. regression constant term b ..............
k Power Regression Graph Power regression expresses y as a proportion of the power of x. The standard power regression formula is y = a × xb, so if we take the logarithm of both sides we get ln y = ln a + b × ln x. Next, if we say X = ln x, Y = ln y, and A = ln a, the formula corresponds to linear regression formula Y = A + bX. 1(CALC)6(g)4(Power) 6(DRAW) The following is the power regression model formula. y = a·xb a .............. regression coefficient b ..............

When these graphs are displayed, the paired-variable calculation results appear as shown below when you press 1(CALC)1(2-VAR). • Use c to scroll the list so you can view the items that run off the bottom of the screen. o ........... mean of data stored in xList Σy2 ........ sum of squares of data stored in yList Σx .........
4. Performing Statistical Calculations All of the statistical calculations up to this point were performed after displaying a graph. The following procedures can be used to perform statistical calculations alone. u To specify statistical calculation data lists You have to input the statistical data for the calculation you want to perform and specify where it is located before you start a calculation. Display the statistical data and then press 2(CALC)6(SET). The following is the meaning for each item.
k Paired-Variable Statistical Calculations In the previous example under “Displaying the Calculation Results of a Drawn Paired-Variable Graph”, statistical calculation results were displayed after the graph was drawn. These were numeric expressions of the characteristics of variables used in the graphic display. These values can also be directly obtained by displaying the List Editor and pressing 2(CALC)2(2-VAR).
u Calculation of the Correlation Coefficient (r), Coefficient of Determination (r2) and Mean Square Error (MSe) After the regression formula parameters on the regression calculation result screen, the following parameters also appear on the display.

5. Tests The Z Test provides a variety of different standardization-based tests. They make it possible to test whether or not a sample accurately represents the population when the standard deviation of a population (such as the entire population of a country) is known from previous tests. Z testing is used for market research and public opinion research, that need to be performed repeatedly. 1-Sample Z Test tests for the unknown population mean when the population standard deviation is known.
The following pages explain various statistical calculation methods based on the principles described above. Details concerning statistical principles and terminology can be found in any standard statistics textbook.

F value p ....................... p-value df ..................... degrees of freedom SS ..................... sum of squares MS ................... mean squares With Two-Way ANOVA, you can draw Interaction Plot graphs. The number of graphs depends on Factor B, while the number of X-axis data depends on the Factor A. The Y-axis is the average value of each category.
Define List 3 (the data for each group) as Dependent. Define List 1 and List 2 (the factor numbers for each data item in List 3) as Factor A and Factor B respectively. Executing the test produces the following results. • Time differential (A) level of significance P = 0.2458019517 The level of significance (p = 0.2458019517) is greater than the significance level (0.05), so the hypothesis is not rejected. • Temperature differential (B) level of significance P = 0.
6. Confidence Interval A confidence interval is a range (interval) that includes a statistical value, usually the population mean. A confidence interval that is too broad makes it difficult to get an idea of where the population value (true value) is located. A narrow confidence interval, on the other hand, limits the population value and makes it difficult to obtain reliable results. The most commonly used confidence levels are 95% and 99%.
u General Confidence Interval Precaution Inputting a value in the range of 0 < C-Level < 1 for the C-Level setting sets a value you input. Inputting a value in the range of 1 < C-Level < 100 sets a value equivalent to your input divided by 100. k Z Interval u 1-Sample Z Interval 1-Sample Z Interval calculates the confidence interval for an unknown population mean when the population standard deviation is known. Perform the following key operations from the List Editor.
u 1-Prop Z Interval 1-Prop Z Interval uses the number of data to calculate the confidence interval for an unknown proportion of successes. Perform the following key operations from the List Editor. 4(INTR) 1(Z) 3(1-PROP) Data is specified using parameter specification. Calculation Result Output Example u 2-Prop Z Interval 2-Prop Z Interval uses the number of data items to calculate the confidence interval for the difference between the proportion of successes in two populations.
The following shows the parameter data specification items that are different from list data specification. Calculation Result Output Example u 2-Sample t Interval 2-Sample t Interval calculates the confidence interval for the difference between two population means when both population standard deviations are unknown. The t interval is applied to t distribution. Perform the following key operations from the List Editor. 4(INTR) 2(t) 2(2-SAMPLE) 7.
Normal probability density calculates the probability density of normal distribution from a specified x value. Normal cumulative distribution calculates the probability of normal distribution data falling between two specific values. Inverse normal cumulative distribution calculates a value that represents the location within a normal distribution for a specific cumulative probability. Student-t probability density calculates t probability density from a specified x value.
• V-Window settings for graph drawing are set automatically when the Setup screen’s “Stat Wind” setting is “Auto”. Current V-Window settings are used for graph drawing when the “Stat Wind” setting is “Manual”. • After drawing a graph, you can use the P-CAL function to calculate an estimated p-value for a particular x value. The P-CAL function can be used only after a Normal Probability Density, Student-t Probability Density, 2 Probability Density, or F Probability Density graph is drawn.

k Data (Constants, Text, Formula) Input Basics First let’s have a look at a few basic procedures that apply regardless of the type of data you are inputting. u To overwrite data currently in a cell with new data 1. Move the cell cursor to the cell where you want to input data. • If the cell you select already contains data, the following step will overwrite the existing data with new input. 2. Use the calculator’s keys to input data.
k Inputting a Constant (Value, Calculation Result, Number Sequence) into a Cell A constant is something whose value is fixed as soon as you finalize its input. A constant can be either a numeric value, or a calculation formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign (=) in front of it. Inputting sdaw, for example will cause the value 0.5 (the calculation result) to appear in the cell (when Deg is selected as the Angle unit).
Item 1st Cell Description Input the reference name (A1, B2, etc.) of the cell where you want the first value of the number sequence to be input. Specify a cell here only if the starting cell is different from the one you specified in step 1 of this procedure. Example: al(B)bw (B1) • Each time you press w after inputting data for a setting item, the highlighting will move to the next setting item. You also can use f and c to move the highlighting upwards and downwards as required.
u Formula Input Example A 1 B PRICE C QUANTITY TOTAL 2 35 15 525 3 52 15 780 4 78 20 1560 Procedure 1. Input the text for line 1, and the applicable values in cells A2 through B4. 2. Move the cursor to cell C2, and input the formula for A2 × B2. !.(=)av(A)c*al(B)cw 3. Copy the formula in cell C2 and copy it into cells C3 and C4. Move the cell cursor to cell C2 and then perform the following operation.
u To input a cell reference name using the GRAB command Move the cell cursor to cell B1 and then perform the following operation. !.(=)1(GRAB)d1(SET)+fw • Commands 2(GO) through 6(BTM→) on the submenu that appears when you press 1(GRAB) are identical to commands 1(GO) through 5(BTM→) of the JUMP command submenu. See “Using the JUMP Command to Move the Cell Cursor” on page 9-7 about these commands.
k Specifying Cell Formatting For each cell, you can specify the text color, cell color, and cell color lightness (Normal or Lighter). u To specify cell formatting 1. Select the range of cells whose formatting you want to specify. 2. Press !f(FORMAT) to display the FORMAT dialog box. 3. Configure the above dialog box with the following settings. To specify this: Perform this operation: Specify the text color Press b(Char Color) and then use keys b through i to specify the desired color.
k Copying and Pasting Cell Contents You can copy the contents of one or more cells and paste them into another location. Once you perform the copy operation, you can copy the contents to multiple locations, if you want. u To copy and paste spreadsheet data 1. Select the cell(s) you want to copy. • See “To select cells” (page 9-6) for more information. 2. Press 2(EDIT)2(COPY). • This will go into paste standby for the selected data, indicated by the 1 menu item changing to (PASTE).
When you are cut and paste a range cells, reference names that affect relationships within the range are changed accordingly when the range is pasted in order to maintain the correct relationship, regardless of whether they are relative or absolute reference names. → Cutting the B1:C1 range of cells that includes the formula =B1+5 and pasting it into B2:C2.
k Inputting the Same Formula into a Range of Cells Use the Fill command when you want to input the same formula into a specified range of cells. The rules governing relative and absolute cell name references are the same as those for copy and paste. When you need to input the same formula into cells B1, B2, and B3, for example, the Fill command lets you do so by inputting the formula once, into cell B1. Note the following about how the Fill command handles cell name references in this case.
k Sorting Constant Data Note that only constant data can be sorted. You can select multiple columns within a single line or multiple lines within a single column for sorting. u To sort constant data 1. Select a range of column cells in a single row or a range of row cells in a single column. • See “To select a range of cells” (page 9-7). • A Syntax ERROR message will appear if any of the cells in the range you select contain data other than constant data. 2.
u To insert a row or column of blank cells 1. Perform one of the following operations to specify the location of the insert and the number of rows or columns to be inserted. • To insert rows Starting with the row immediately below of the row where you want the insert to be performed, select the same number of rows that you want to insert. Example: To insert three rows above row 2, you could select A2:A4, B2:C4, etc.
3. Using Special Spreadsheet Mode Commands The Spreadsheet mode has a number of special commands like CellSum(, which returns the sum of a range of cells, and CellIf(, which specifies branching conditions. These special commands can be used inside of formulas. k Special Spreadsheet Mode Command List “Input Key Operation” operations can be performed during cell input only. You can omit anything enclosed in brackets ([ ]) in the Syntax of each command.
Command Description CellMedian( (Median of Cells) Returns the median value in a specified range of cells. Input Key Operation: 5(CELL)4(Med) Syntax: CellMedian(start cell:end cell[)] Example: =CellMedian(A3:C5) Returns the median value of the data in cell range A3:C5. CellSum( (Sum of Cells) Returns the sum of the data in a specified range of cells. Input Key Operation: 5(CELL)5(Sum) Syntax: CellSum(start cell:end cell[)] Example: =CellSum(A3:C5) Returns the sum of the data in cell range A3:C5.
4. Conditional Formatting The conditional formatting function can be used to define conditional expressions (such as A1<0) that determine the formatting (text color, area color, paint style) of a cell. k Conditional Formatting Overview You can specify up to two conditions for each cell. Pressing 6(g)5(CONDIT) displays the Condition screen. To select a particular condition, move the highlighting to the “Condition” line and then press 1(COND1) for Condition1 or 2(COND2) for Condition2.
• Type: Expression Use this condition type to define a condition based on a formula (such as CelMin(A1:B10)≤C1) that references one or more cells. This condition type provides a wide range of versatility to set up conditions such as the ones shown below. • When A1×30>100, A1 text is blue. • When CellSum(B1:B30)≤A1, A1 text is blue, and when A1

Use f and c to move the highlighting to “Format” and then press 1(SETFORM). • On the FORMAT dialog box that appears, perform steps 3 and 4 of the procedure under “To specify cell formatting” (page 9-13) to configure format settings. • Including format settings will cause a sample of the format to appear in the “Format” line. → 7. If you want to configure multiple conditions, repeat steps 3 through 6. 8. After the settings are the way you want, press J. • This returns to the screen in step 1.
The following is the basic syntax for inputting values for V1, V2, and Value. • Move the highlighting to the line whose setting you want to change, input a value or calculation formula, and then press w. If you input a calculation formula, the final value will be the calculation result. • If 3(C= ) or 4(C≠ ) is selected for “Expre”, you can specify 2(ERROR) or 3(BLANK) for “Value”. - 2(ERROR) ... Decision depends on whether or not “ERROR” is displayed in the cell whose settings are being configured.
- 2(ERROR) ... Inputs “ERROR” into the conditional expression. For example, you can use this to input A1=ERROR. Decision depends on whether or not “ERROR” is displayed in the cell being referenced in the conditional expression (A1 in the example here). - 3(BLANK) ... Inputs “BLANK” into the conditional expression. Decision depends on whether or not the cell being referenced in the conditional expression is blank. - 4(And) ... Inputs the logical operator “And” into the conditional expression. - 5(Or) ...
u Procedure 1. Select the range of cells B3:C4. 2. Press 6(g)5(CONDIT) to display the Condition screen. • Condition1 appears first, so configure the first condition here. 3. Use c to move the highlighting to “Expre” (Expression) and then press 6(g)1(C< ). • Initially, “Cell < Value” is displayed in the Expre line. 4. Use c to move the highlighting to “Value” and then press aw to input 0. 5. Use c to move the highlighting to “Format” and then press 1(SETFORM).
5. Drawing Statistical Graphs, and Performing Statistical and Regression Calculations When you want to check the correlation between two sets of data (such as temperature and the price of some product), trends become easier to spot if you draw a graph that uses one set of data as the x-axis and the other set of data as the y-axis. With the spreadsheet you can input the values for each set of data and draw a scatter plot or other types of graphs.
