Question about Casio FX-115ES Scientific Calculator

Yes and here is how to do 1-var statistics and 2-var statistics. Please read the whole post. 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.

In statistic, do I need to retype the same sample ( about 30 numbers) each time I need to calc statistical function such as Sum, sum^2, standard deviation, average etc...

I notice once I calc - or use statistical funtion n, when I repeated again #n is increase.

Is it the same if I use the statistical function for others too?

Hi there,

Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

Here's a link to this great service

Good luck!

SOURCE: Casio FX-115 ES: SIN,COS,TAN (answer isnt correct)

Hello,

It may be due to the angle unit used. You can have angles in
degrees, in radians, and in grads. You should set the default angle
unit to waht you problem calls for.

To set degree as default SHIFT MODE 3

To set radians as default SHIFT MODE 4

To set grads as default SHIFT MODE 5

The
values of angles calculated by the inverse trigonometric functions are
in the default unit that is set . This may be the source of the wrong
answers that you get.

Hope it helps.

Sorry, It is not possible to solve equations on the Casio FX-82 ms. Try the Casio FX-115 ES/ FX-115 ES Plus, FX-991ES/ FX-881 ES Plus C.

The Casios FX-115 ES , FX-115 ES PLus, FX-991 ES, FX-991 ES Plus C can perfom numerical differentiation at a point, and numerical integration between two given limits.

The FX-901 calculator seems to be the equivalent of the FX 260 Solar sold in North America. It does fraction calculations, permutation, statistics but lack the Equation Solver.

You cannot use it to solve equations.

Casio Scientific calculators that can handle equation solving are the FX-115 and FX-991.

Simplify your first equation by dividing all its terms by 3, then use elimination to carry out the solution by hand.

There must be an error in what you report. You pressed MODE then 4: Base-N and now your calculator is in base-N calculation mode (the DEC, Hex, BIN, OCT) numeration keys are active.

To do statistics you must put the calculator in STATS mode.

Press MODE: You have 6 computational modes to choose from

1: COMP, the general computational mode

2:CMPLX, for calculation s with complex numbers,

3: STAT for statistics,

4: Base-N, binary, octal, decimal, and hexadecimal numeration

5: Equation, solving mode, etc..

**For statistics, choose 3:STAT**

Try reseting it by pressing "shift" , "9" , and "3" in that order after you turn it on. It might fix it mine did the same thing and it fixed it.

I took statistics last semester and I don't really remember how, but after you enter your data, you press SHIFT, then STAT (on the 1 key), then I think it's under 5 (VAR), and maybe Xon-1? Eh, funny how long you remember this stuff for....
