    One (or more) of your arguments is outside the domain of possible arguments. For example, with the chi-square density functions the degrees of freedom must be a positive integer.

    Could you post the specific function and arguments?

If your solution comes out negative, it will say this because x^2 can never be negative. therefore, your answer is out of the domain of the function and will not register because it isnt a real solution
what function are you using?

Err domain


You tried to use an argument to a function that was not in the function's domain. For example, the arcsine function takes an argument from negative one to positive one. Trying to take the arcsine of 2 will generate a domain error.

If you need further assistance, please specify the exact function and argument that is generating this error.

I want to do a chi-square test on the TI-85


The chi-square test is used for a lot more than just contingency tables.

I found one program for the TI-86 (which is basically the same machine as the TI-85, only with more memory) which claims to do the chi-square goodness of fit test.

Whenever i try the graph on my TI-83 Plus the ERR:INVALID DIM 1:QUIT comes up and ive checked the STAT PLOT and i have Plot 1 set as ON.


You have to turn all statistical plots OFF before you draw function graphs. Press [2nd][Y=] to open the statistical plot configuration screen. Press [4:PlotsOFF] and then [ENTER]. When calculator answers DONE you are ready to draw function plots.

TI-83 Plus Calculator: what does ERR: DIM MISMATCH mean?...


Imagine you are doing statistical calculations with two list, say L1 and L2 but one list has 10 elements (values) while the other has only 9. The dimension of the lists are different (mismatched) because one is 10 and the other 9.

Another case is if you are manipulating matrices such as adding a3x3 matrix to 3x2 matrix. Both matrices have the same number of rows but different numbers of columns.

Clearing or correcting an error message on the TI-83 Plus


Press [STAT] to open the Statistics editor. From the menu that displays, select PlotsOFF and press [ENTER] twice. The calculator answers "Done".
Open the [Y=] editor to enter the functions to be drawn. Use the Trace ONLY after the graph has been displayed.

To clear any message without necessarily removing the conditions that yield the error press the CLEAR button.

I don't have a chi square goodness of fit test, where can i find?


You can find the chi-square test for two-way tables and the chi-square goodness of fit tests in the STAT TEST menu (STAT Left).

You can find the chi-square probability density function in the DISTR menu (2ND [DISTR])
