Question about Casio Fx-9750g Plus
HELP! I'm suddenly getting "DIM Error" whenever I add data into list 1 in Stat mode and then go "CALC" It is happening when I choose both the 1 Var and REG options. I've been using this calculator for about a week and its been absolutely fine doing those exact things and now suddenly I'm getting the error every single time! I've tried clearing the memory and resetting the calculator but neither has solved the issue - still getting the error. I have a test in the morning and need to be able to use these functions! Help! Thanks

Here are the possible causes for such an error
1. calculation results exceeds calculation range.
2. Calculation is outside the input range of a function
3. Illogical operation (division by zero, etc.
4. Poor precision in sigma calculation results,
For all these reasons
Check the input numeric values and correct them . If you are using memory, check that the numeric values stored in memory are correct.
Hope it helps

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:
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.
