Having gone over a month with no response, I assume this is no longer a problem.

SOURCE: i'm trying to find a chi squared test statistic

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?

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.

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

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.

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.

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.

If the message appears when you try to graph functions deactivate the
statistical plots. To do so:

Press [2nd][Y=] to access (STAT PLOTs)

Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.

If the message appears in another context, it sure would help knowing the context of the error.

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.

Easy:

1.) Turn it on ("ON" button)

2.) Hit the "STAT" button

3.) Hit the Right arrow key Twice

4.) Hit the down arrow key once or hit the "2" button

5.) Enter your Data into List one (L1) OR Right Arrow once and "ENTER" to just enter your statistics

To just Enter the Statistics:

Down Arrow once and Enter:

Hypothesis mean

Sample Mean

Standard Deviation

Number of Tests

and Either (not equal to)Ho , <Ho , or >Ho

Then either hit Calculate or Draw

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])

Are you putting a non-integer into the degrees-of-freedom argument? If you're not sure, why don't you post the arguments you're trying to use?
