I want to study chi square test of homogeneity from any authentic source- book / website especially problems where samples are compared for more than one attribute.
'Chi square test of homogeneity is a Chi square test that determines whether two or more independent random samples are from the same or different population.'
What are some relevant sources?
Relevant background:
I was studying examples from random online sources before I saw this book in which a second X2 has been calculated and is substracted from the principle X2 (the one we usually find). This is inconsistent to the examples I saw online.
Here are two links to the process from the book I'm talking about:
1.https://i.stack.imgur.com/6KZQc.png
2.https://i.stack.imgur.com/rjFvk.png
In fact we are being taught the latter process. I'm not sure which one is correct to find the chi square of homogeneity.

I have a question regarding Yates' correction and I can't accommodate the text due to character limits here so here's a link to the question: https://i.stack.imgur.com/suGfa.png
