Hi everyone Im really sorry if I've posted in the wrong section but I didn't have a clue where to post this!

Anyway I've been given an assessment in which I have to use chi squared but I haven't got a clue how to do it! I've asked the teacher as I wasn't there when she explained it and apparently she has no time to tell me so this is my only hope!

I've tried reading up on google but the sites tell you different things and in complicated ways!

So could anyone please tell me step by step how to do the chi squared test please?

Thank youu
