Question about Sharp EL-738 Scientific Calculator

Open Question

EL738 -- area under the normal curve?

My financial/statistical calculator has functions to get me the mean and sigma etc. From there, it should have been easy to get to the probability (area under the normal curve left of Z).

Does this function exist on the EL738?

Hello,
To raise a number to some power other than 2 or 3, you use the [y to the x] key. Exemple 2[y to the x] 5 = 2x2x2x2x2=32.
Hope it helps.

PS. I could not understand what you wanted with those expressions.

SOURCE: how do you use the statistics function to find out

Press [2ndF][MODE][1] to select single variable statistics.

  1. Enter a value and press [DATA]
  2. or enter value, press [X,Y]key, enter the frequency then press [DATA
When finished you can access the mean (xbar an X with a small horizontal bar like a minus sign on top of it.)

The xbar may be a key accessed directly if xbar symbol is on top of the key, or a [2ndF] key if xbar is written on the body of the calculator.

Can you please help me on how to calculate mean, median, mode, standard deviation calculation on casio fx-991ms scientific calculator


This will show you how to do statistics (calculate average, standard deviation, regressions etc.) as to the mode and median refer to the definitions.

TO COMPUTE STANDARD DEVIATION AND 2-VAR STATISTICS.

I assume you know the theory. I will show you the key strokes

For 1-Var statistics
Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.
Enter a number and press [=]. Cursor jumps to second number to enter.
Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.
Press [AC] key to clear the screen.
Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.
Press the number corresponding to the statistical value you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.
To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics
To perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. As I assumed above, you should be able to recognize what each variable means.

Hod do you put this calculator into statistical mode?


The 30XA doesn't have a statistical mode; all of the statistical functions are available at all times.

2nd [CSR] clears the statistical registers, Sigma+ adds a data point, Sigma- deletes a data point, 2nd [x-bar] gives the mean, 2nd [sigma-x-n] and 2nd [sigma-x-n-minus-one] give the population and sample standard deviation.

For full details, refer to the statistics section in the manual. If you don't have a manual, you can download a guidebook from

Hello. I just wanted to ask you how do I calculate the variance and standard deviation in my cfx9850GB plus. I had a quick look at the manual but I couldnt find the info. thankz .


This shows you how to enter your data and calculate some statistical values. Keep in mind that the variance is the square of the standard deviation.


In the main menu select [STAT] icon to enter Stat mode and display the statistical data lists. Use the statistical data lists to input data and perform statistical calculations. Use the arrows to move the highlighting around the lists.
Example: Enter the following values in List 1
1st line enter 90 [EXE]
2nd line 85 [EXE]
3 79 [EXE]
4 75 [EXE]
5 70 [EXE]
6 68 [EXE]
7 56 [EXE]

When finished you press [F2:Calc], then [F1:1Var] and the statistical results appear on screen.

Title of screen : 1-Variable
x bar =74.7142857
Capital Sigma x= 523
Capita Sigma X squared = 39851
x lower case sigma n = 10.5249945
x lower case sigma n-1= 11.3682934
n = 7
Scroll down with Down arrow to access other data
minX =56
Q1=68
Med =75
Q3=85
Xbar -x lower case sigma n =64.1892911
x bar x lower case sigma n = 85.2392802
maxX=90
Mod=90

All you have to do now, is to look at the theory you learned and interpret what these values mean.

How to use graphing calculator?


The casio FX-300Ms calculator cannot do graphs. To tell you how to use a graphing calculator TO DRAW GRAPHS we need to know the exact brand and model number of the calculator.

  1. Most graphing calculators basically function the same way.
  2. You select the graph type (function, polar,parametric, sequence, 3D, wire mesh, slope field, etc.)
  3. You enter the algebraic form of the function you want to draw.
  4. You press a button or menu to GRAPH
  5. The graph is drawn.
  6. If you want to see a particular part of the graph, you use a ZOOM function, or you enter values for the WINDOW dimensions.
  7. Most graphing calculators have a TRACE function that allow you to follow the curve you have drawn to read off values of coordinate points.
  8. You can also use the calculator to find zeros roots) of functions, calculate derivatives at some chosen points or calculate the area "under the curve", find the minimum and maximum of a function.
In addition to its graphing capabilities, a graphing calculator can be used as a scientific calculator. Sometimes it can also do statistical and financial calculations, matrices, list manipulations, operations on complex numbers, text editing,, creating programs etc.

How do i use this calculator (casio CFX 9850)to find the variance


Part A shows you how to enter your data and calculate some statistical values. Keep in mind that the variance is the square of the standard deviation.

You can safely ignore the PART about REGRESSIONs until that time you need the information.

PART A
In the main menu select [STAT] icon to enter Stat mode and display the statistical data lists. Use the satistical data lists to input data and perform statistical calculations. Use the arrows to move the highlighting around the lists.
Exemple: Enter the following values in List 1
1st line enter 90 [EXE]
2nd line 85 [EXE]
3 79 [EXE]
4 75 [EXE]
5 70 [EXE]
6 68 [EXE]
7 56 [EXE]

When finished you press [F2:Calc], then [F1:1Var] and the statistical results appear on screen.
Title of screen : 1-Variable
x bar =74.7142857
Capital Sigma x= 523
Capita Sigma X squared = 39851
x lower case sigma n = 10.5249945
x lower case sigma n-1= 11.3682934
n = 7
Scroll down with Down arrow to access other data
minX =56
Q1=68
Med =75
Q3=85
Xbar -x lower case sigma n =64.1892911
x bar + x lower case sigma n = 85.2392802
maxX=90
Mod=90

All you have to do now, is to look at the theory you learned and interpret what these values mean.


PART B
  1. Once you enter your data [MENU][STAT],
  2. press [F1:Graph],
  3. select Gph1, Gph2, or Gph3.
  4. Once the graph of the experimental data is drawn, you will have access to the diverse regression models.
  5. Your choices are
  • [X:Linear]
  • [Med-Med],
  • [Quadratic :X^2]
  • [Cubic;X^3]
  • [Quartic: X^2].
  • Press [F6] to scroll right to access the others:
  • [Logarithmic:LOG],
  • [Exponential :EXP],
  • [Power :Pwr] and
  • [Sinusoidal:Sin]
  1. After you select a model and press [EXE], the screen displays the equation and its various coefficients.
  2. On that same screen, you have a menu option [F6:Draw].
  3. If you select it, the regression curve will be drawn on the same screen as your statistical graph.
  4. This allows you to judge if the fit is good. If it is not, you have the option to choose another model.
  5. The other option [F5:Copy] allows you to save the regression equation in the Y1, Y2, etc. variables.

Standard Deviation


Hello,
If you want to do statistics with this calculator you press [MODE][3:STAT]. You have then 8 options 1:1-var, 2:A+BX, etc.
For one variable statistics you press 1. Enter the values for the X variable in the template. Once finished you press [SHIFT][1](STAT) then select the value you want ( n, x bar , and the standard deviations (X sigma n) and (X sigma n-1).
Hope it helps.
