I am not sure I understand the question, but if you are asking about how to compute a Chi Square statistic and its meaning when one confronts contingency tables, I have written a brief notebook for my class. I'm attaching it to this post.

Hi Christine,

In further calculations shows the p-Value for the PearsonChiSquareTest : 0.0496.

\[ScriptCapitalH] = 
 PearsonChiSquareTest[data, Automatic, "HypothesisTestData"]
\[ScriptCapitalH]["PValueTable"]
p = PearsonChiSquareTest[data]

Good Luck,.......Jos

Try reading:

or

https://www.wolfram.com/language/elementary-introduction/

those two will explain simple list-manipulation and import et cetera,

Hi, Yes I did look at the references many times. I am now taking a class so I am unfamiliar with the concept. Also, I am a first time user to Wolfram. I have no idea how to use my data and follow the Reference Guide to input the data into the formula bar. So unfortunately, the link doesn't help me much because I don't know how to interpret it into Wolfram nor do I understand what I'm doing. Sorry for my lack of understanding but you'll have to go step by step with me on this because I'm completely clueless.

Thanks.

What did you try yourself? Have you looked for Chi square test? You would've found: http://reference.wolfram.com/language/ref/PearsonChiSquareTest.html

With a plethora of examples. Good luck!
