Question about Casio FX-115ES Scientific Calculator

The older version for entering data is by using a semicolon.

x:f for eg 2;3 M+

4;5 M+ and so on.

The new casio calulator has no semicolon. How to enter the above data in SD mode in order to find SD and mean?

Here is what I gather from the picture of the faceplate.

You choose the standard deviation mode (SD) by pressing MODE 3.

You might have to choose 1-Var or 2-Var. (not sure, but 1-var for sure)

You enter a data item followed by the DATA (RUN) key. Keep entering data and pressing RUN.

While in SD MODE, if you press the 1 key you get the avregae xbar, if ****** you get the sum of squares of the entered data. Looking at the digit keys, They all have statistical markings: (A, B, and r) are for regression analysis, (7,8, 9). 2 has the population standard deviation sigma n x, 3 the sample SD, etc. That should get started. And please, experiment. There are not many variations, on th statistical theme on scientific calculators.

Hope it helps.

In Run screen press [SHIFT][MODE] to enter SetUp.

Look for the line Input Mode (it is the 1st on the SD version). Highlight the line then press the TAB at the bottom of screen that says Lin (F2 key). Press EXE when you finish with SetUp.

To use the logab( function,

1. open the Run/Mat screen.

2.Press the OPTN key.

3.Press [F4:Calc].

4. Press [F6:].

5. Press [F4:logab]

the command is displayed on the screen,.

6. Enter the base then the argument).

7. Close parenthesis if you want and

8. press EXE.

Example logab(2,8) =3

When you press MODE 6 for Matrix, you're clearing any previously entered matrices. So, you're clearing MatA when you go to enter MatB.

Instead, after entering MatA press SHIFT 4 to bring up the Matrix menu, press 1 for DIM, press 2 for MatB, press 5 for 2x2, and enter the data.

- Calculator must be in SD mode (standard deviation mode) :Press [MODE] [.]
- However, if [FIX] or [SCI] appears on display you must press [MODE][9] first.
- Data input always starts with [SHIFT][SAC], to clear the registers of old data.
- Type a number and press the [DATA] key, it is the [M+] key at the bottom right of keypad.

Press [SHIFT] [9] (sigma n-1) to get sample standard deviation

Press [SHIFT][8] (sigma n] for the population standard deviation

Press [SHIFT] [7] (xbar) for the mean

Press [SHIFT] [6] (n) for the number of data entries

Press [SHIFT] [5] (capital sigma x) for the sum of values

Press [SHIFT] [4] (capital sigma x to y) for the sum of squares of the values

For additional information you might consider taking a look at the calculator manual

If you want to get an answer like 1/2X for d/dx(X^2), you will have to
purchase a CAS calculator like Casio's Algebra FX-2 or Classpad. TI series calculators also have CAS.

However, you can calculate the numerical values of derivatives and integrals only.

To calculate the value of a proper integral:

**∫**xdx from 0 to 2, input as follows:

**∫**dx(X,0,2)

To calculate derivative at a point:

SHIFT+**∫**dx key X^2,3)

Display looks like this: d/dx(X^2,3).

However, you can calculate the numerical values of derivatives and integrals only.

To calculate the value of a proper integral:

- Press the 'ON' key;
- Press the Integral key ;
- Enter your expression (example X^2+X-3 etc);
- Press the 'comma' key after your expression;
- Input the first limit after comma, input comma again after first limit;
- Close brackets;
- Press the equals key, display may return after a while with the answer.

To calculate derivative at a point:

- Press Shift and then the integration key.
- Enter your function;
- Input comma;
- input the point at which you want to evaluate the derivative;
- Close bracket and press enter.

SHIFT+

Display looks like this: d/dx(X^2,3).

Hello,

Find on the calculator the [nPr] key either (you may have to use the [2nd] or [2ndF] key) then

1. Enter the number that corresponds to n eg. 18

2. Press the [nPr] key

3. Enter the number that corresponds to r eg. 5

18[nPr]5 gives 1028160

If you calculate combinaitions use [nCr] key.

Hope it helps

Click
on the Mode button twice until you see
“SD”. Select 1. This puts the calculator in Statistics Mode.
Enter the first number, 1.

Hit the M+. (n= 1 will appear in the window)

Enter the second number, 1.

Hit the M+ key. (n=2 will appear in the window)

. . . . .

Enter the last number, 7.

Hit the M+ key. (n=7 will appear in the window)

Hit shift, 2. (This invokes the S-Var option.)

Hit 1 for the sample mean. Hit Enter.
