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.

There are several applications missing on my ti-84. I don't have tcdf, chi squared cdf, or chi squared GOF test. How can I get these on my calculator?


Those functions are in the DISTR menu, accessible by pressing 2ND [DISTR].

If you need any of them, you can download apps from

How do you find out chi squared on a casio fx 9860G SD calculator?


The following screen captures are from another Casio Graphing calculator so the menu screen may not look yours. However the instructions are identical.

Here is a sequence of screen captures to illustrate how to do it.
Turn calculator ON. Use arrow to highlight STAT and press EXE

Choose Cpd or Ccd

If you choose Cpd : you must enter the Chi value you want, and press EXE, then the number of degrees of freedom (df) and press EXE. The Execute command is highlighted. This allows you to perform the actions
indicated by the Thumbnails at the bottom of the screen: calculate a value or Draw the distribution.

In the example above I took Chi=1, and df=3 and pressed the CALC menu.

If I press the DRAW menu instead, the distribution is displayed.

If you want the other distribution Ccd, press Ccd instead in screen capture 4.

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])
