Question about Texas Instruments TI-85 Calculator

I am learning about contingency tables in my statistics class, and would like to be able to use the TI-85 to perform the chi-squared test rather than doing it by hand. The TI-83 will do it, so I am wondering if somebody has a program or a method that will work on the 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.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

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?

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

Hey there,

You are looking for the cube root function which can be found under the MATH menu selection. the answer you get will simply need to be squared and you have your answer

It's in the STATS menu, not the TEST menu.

Press STAT then left-arrow then up-arrow five times.

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

This shows you how to enter your data and calculate some statistical
values. Keep in mind that the variance is the square of the standard
deviation.

In the main menu select [STAT] icon to enter Stat mode and display the statistical data lists. Use the statistical data lists to input data and perform statistical calculations. Use the arrows to move the highlighting around the lists.

Example: Enter the following values in List 1

1st line enter 90 [EXE]

2nd line 85 [EXE]

3 79 [EXE]

4 75 [EXE]

5 70 [EXE]

6 68 [EXE]

7 56 [EXE]

When finished you press [F2:Calc], then [F1:1Var] and the statistical results appear on screen.

Title of screen : 1-Variable

x bar =74.7142857

Capital Sigma x= 523

Capita Sigma X squared = 39851

x lower case sigma n = 10.5249945

x lower case sigma n-1= 11.3682934

n = 7

Scroll down with Down arrow to access other data

minX =56

Q1=68

Med =75

Q3=85

Xbar -x lower case sigma n =64.1892911

x bar x lower case sigma n = 85.2392802

maxX=90

Mod=90

All you have to do now, is to look at the theory you learned and interpret what these values mean.

Quoting from page B-7 of the Guidebook:

-----

You are attempting a stat calculation with lists that are not appropriate; for example, you are requesting a statistical analysis with fewer than two statistical data points. The frequency (y value) for a 1-VAR analysis must be an integer >= 0.

------

If you simply want 1-variable statistics for two sets of data, you'll have to calculate them separately.
