Question about Casio Office Equipment & Supplies

# Whenever I use my casio fx-9750G2 calculator to try to find the mean and standard deviation after entering 1 data set I get the syntax Error message coming up. How can I correct this?

I have tried to clear this by restting the calculator by pressing the reset button on the back.

You should be doing 1-var statistics, not regressions.

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....

Hello,
I am happy that you found my solution helpful and even flattered that you copied it in this thread. By doing this, you gave me the opportunity to discover an error in my post. In fact, the calculator does provide a column for the frequency. If you enter nothing in the frequency column, all data items will have their frequency set to 1, by default.

Back to the current subject: How to get the variance (the square of the standard deviation).
When you finish entering your data:

1. Press the [AC] button to exit the data editor.
2. Press [****][STAT].
3. Press [5:Var] to open the statistical result selection screen.
4. Press [3: xSigma_n] or [4:xSigma_n -1] depending on what you are interested in (population or sample) standard deviation.
5. The screen echoes the symbol for the value selected (the value displayed on the bottom line may be 0 or an old value from a previous calculation: it is not the value you have just calculated).
6. Press [=] to display the current value of the SD chosen.
7. By doing this you are in fact storing it it answer memory.
8. All you have to do now is to raise it to power 2 by pressing the [x^2] key ( the one above the [HYP] key).
9. The calculator will display Ans^2.
10. Press [=] to display the value of the variance.
If you are not interested in the value of the standard deviation, but just want the variance, follow the foregoing procedure until step #5.
While the symbol xSigma_n or xSigma_n-1 is still displayed with the blinking cursor to its right, press the [x^2] key above the [HYP] key. The screen displays say xSigma_n ^2. Press [=] to calculate the variance.

As my motto says, I am always happy to help, but happier still when people show true appreciation.

Hope it helps.

I am not sure how you can create such function (the range limitation do not work for x=c) but you can draw a vertical segment, just do not call it a function.

Draw a graph Y1=0
Then press SKETCH function key and use the F6 key to cycle through the TABS at the bottom of the screen. Look for the TAB named PEN. and click the function key below it.

Use the arrows to move the cursor to a spot on the screen (near the bottom), Press EXE to fix the starting point of the segment. Then use the Up arrow to draw a vertical segment from bottom to top.

### How can i use casio 991ms to solve all statistics questions

first off you want you calculator in SD (standard deviation) mode to do this hit mode twice and then 1.
next it is good practice to start off by clearing the memory to do this hit shift, CLR,1 and then = this will clear statistical memory
to enter values into your data set , you enter the value, then press the DT (M+) button. (note: pressing DT repeatedly will impute the same value multiple times)
once you have finished pluging in your numbers your calculator can give you statistical information about the data set.
hitting shift then 1(S-SUM) gives you three options: 1 the sum of the squares of each value 2 the sum of each value 3 the number of terms in the data set hitting shift then 2 (S-VAR) gives you three more options 1 x bar (the mean) 2 x sigma n (the population standard deviation) 3 x sigma n-1 (the sample standard deviation)
you can use these tools to solve alot of statistical problems i hope this helped

### How do I use the standard deviation function?

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

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.
