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.

Hi,

a 6ya expert can help you resolve that 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.

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

SOURCE: standard deviation

Is there a PDF with the Statistical procedures for this product? I bought my Casio FX-115 used (second hand). No instructions. I need help using the Statistical functions for my Stats classes:

Correlation Coefficient

Standard Deviation/Variance

Chi-Square

x-x(bar) summations

HELP!

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....
