Question about Casio CFX-9850G Plus Calculator

Hello,

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.

Hope it helps.

Here are the capabilities of the Casio calculators.

The screen captures may not look like ones taken from the FX-7400G

plus display but the instructions are accurate.

In stat enter the values in List1 and the frequencies in List2**(if doing paired variable statistics)**

Press the key corresponding to the CALC tab

Press the 1-var tab and you get the results as seen on the screen with title 1-variable.

Other screens show some two-variable stats or regressions.

Use you knowledge of sample standard deviations and

population standard deviation to select which is relevant to your case.

They are given by xsigma-n and xSigma n-1

No, it does not. You will need a graphing calculator such as the Casio FX-9750G Plus or the newer version FX-9750 GII.

Hello,

If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.

Hope it helps.
