5. Numerical Calculations The following explains the numerical calculation operations included in the function menu displayed when * (CALC) ( (CALC) on the fx-7400GII) is pressed. The following calculations can be performed. • {Int÷}/{Rmdr}/{Simp} ... {quotient}/{remainder}/{simplification} • {Solve}/{d/dx}/{d2/dx2}/{°dx}/{SolvN} ... {equality solution}/{differential}/{quadratic differential}/ {integration}/{f(x) function solution} • {FMin}/{FMax}/{3(}/{logab} ...
Under initial default settings, this calculator automatically simplifies fraction calculation results before displaying them. Before performing the following examples, use the Setup screen to change the “Simplify” setting from “Auto” to “Manual” (page 1-29). • When “a+bi” or “rQ” is specified for the Setup screen “Complex Mode” setting, fraction calculation results always are simplified before being displayed, even if the “Simplify” setting is “Manual”.
Variable table input is used with the Solve function in the EQUA mode. This input method is recommended for most normal Solve function input. An error (Time Out) occurs when there is no convergence of the solution. For information about Solve calculations, see page 4-4. • You cannot use a quadratic differential, 3, maximum/minimum value or Solve calculation expression inside of any of the above functions.
I Differential Calculations [OPTN]-[CALC]-[d/dx] To perform differential calculations, first display the function analysis menu, and then input the values using the syntax below.
• Inaccurate results and errors can be caused by the following: - discontinuous points in x values - extreme changes in x values - inclusion of the local maximum point and local minimum point in x values - inclusion of the inflection point in x values - inclusion of undifferentiable points in x values - differential calculation results approaching zero • Always use radians (Rad mode) as the angle unit when performing trigonometric differentials.
• Input of the tolerance (tol) value and the closing parenthesis can be omitted. • Specify a tolerance (tol) value of 1E–14 or greater. An error (Time Out) occurs whenever no solution that satisfies the tolerance value can be obtained. • The rules that apply for linear differential also apply when using a quadratic differential calculation for the graph formula (see page 2-24).
Example To perform the integration calculation for the function shown below, with a tolerance of “tol” = 1E – 4 5 1 (2x2 + 3x + 4) dx Input the function f (x). * (CALC)* (°dx)ATV BT C * fx-7400GII: (CALC) Input the start point and end point. @ D Input the tolerance value. @$ C U Note the following points to ensure correct integration values.
Integration Calculation Precautions • In the function f(x), only X can be used as a variable in expressions. Other variables (A through Z excluding X, r, Ƨ) are treated as constants, and the value currently assigned to that variable is applied during the calculation. • Input of “tol” and closing parenthesis can be omitted. If you omit “tol,” the calculator automatically uses a default value of 1E–5. • Integration calculations can take a long time to complete.
I Maximum/Minimum Value Calculations [OPTN]-[CALC]-[FMin]/[FMax] After displaying the function analysis menu, you can input maximum/minimum calculations using the formats below, and solve for the maximum and minimum of a function within interval a x b.
6. Complex Number Calculations You can perform addition, subtraction, multiplication, division, parentheses calculations, function calculations, and memory calculations with complex numbers just as you do with the manual calculations described on pages 2-1 to 2-14. You can select the complex number calculation mode by changing the Complex Mode item on the Setup screen to one of the following settings. • {Real} ...

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.
• List The initial default statistical data is List 1 for single-variable data, and List 1 and List 2 for paired-variable data. You can specify which statistical data list you want to use for x-data and y-data. • Frequency Normally, each data item or data pair in the statistical data list is represented on a graph as a point. When you are working with a large number of data items however, this can cause problems because of the number of plot points on the graph.
• Display (pie graph value display setting) • {%}/{Data} ... For each data element {display as percentage}/{display as value} • % Sto Mem (Specifies storage of percentage values to a list.) • {None}/{List} ... For percentage values: {Do not store to list}/{Specify List 1 to 26 and store} When “Box” (med-box graph) is selected as the Graph Type: • Outliers (outliers specification) • {On}/{Off} ...
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 “Changing Graph Parameters” on page 6-1 to make the settings you want before drawing each graph.
The display screen appears as shown above before the graph is drawn. At this point, you can change the Start and Width values. I Med-box Graph This type of graph lets you see how a large number of data items are grouped within specific ranges. A box minX encloses all the data in an area from the first quartile (Q1) to the third quartile (Q3), with a line drawn at the median (Med). Lines (called whiskers) extend from either end of the box up to the minimum (minX) and maximum (maxX) of the data.
I Normal Distribution Curve The normal distribution curve is graphed using the normal distribution function. 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. I Broken Line Graph Lines connect center points of a histogram bar. XList specifies the list where the data is input, while Freq specifies the list where the data frequency is input.
• Press (DRAW) to return to the original single-variable statistical graph. • When Mod has multiple solutions, they are all displayed. • You can use the Setup screen’s “Q1Q3 Type” setting to select either “Std” (standard calculation) or “OnData” (French calculation) for the Q1 and Q3 calculation mode. For details about calculation methods while “Std” or “OnData” is selected, see “Calculation Methods for the Std and OnData Settings” below.
Center Point 1 2 Center Point 3 4 5 6 7 8 9 Median 2+3 = Q1 2 7+8 = Q3 2 S OnData The Q1 and Q3 values for this calculation method are described below. Q1 = {value of element whose cumulative frequency ratio is greater than 1/4 and nearest to 1/4} Q3 = {value of element whose cumulative frequency ratio is greater than 3/4 and nearest to 3/4} The following shows an actual example of the above.
3. Calculating and Graphing Paired-Variable Statistical Data I Drawing a Scatter Diagram and xy Line Graph The following procedure plots a scatter diagram and connects the dots to produce an xy line graph. 1. From the Main Menu, enter the STAT mode. 2. Input the data into a list. 3.

I Graphing Statistical Calculation Results While the parameter calculation result is on the display, you can graph the displayed regression formula by pressing (DRAW). I Linear Regression Graph Linear regression uses the method of least squares to plot a straight line that passes close to as many data points as possible, and returns values for the slope and y-intercept (y-coordinate when x = 0) of the line. The graphic representation of this relationship is a linear regression graph.

I 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 In y = In a + b × In x. Next, if we say X = In x, Y = In y, and A = In a, the formula corresponds to linear regression formula Y = A + bX. (CALC) (E) (Pwr) (DRAW) The following is the power regression model formula. y = a·xb a .............. regression coefficient b ..............
While the statistical data list is on the display, recall the Setup screen to specify a LIST (“List 1” through “List 26”) for “Resid List”. Calculated residual data is stored in the specified list. The vertical distance from the plots to the regression model will be stored in the list. Plots that are higher than the regression model are positive, while those that are lower are negative. Residual calculation can be performed and saved for all regression models.
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. S 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 (CALC) (SET). The following is the meaning for each item.
These values can also be directly obtained by displaying the statistical data list and pressing (CALC) (2VAR). After this, pressing D or A scrolls the statistical calculation result display so you can view variable characteristics. For details on the meanings of these statistical values, see “Displaying the Calculation Results of a Drawn Paired-Variable Graph” (page 6-14).

6. Confidence Interval Important! • Confidence interval calculations cannot be performed on the fx-7400GII. 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.
