i am currently writing my research proposal for next year and ive come up with a null hypothesis. to try and prove it i want to ask two different groups of people three different questions. these two groups are employees of companies and general consumers. the questions are the same for the two groups.

i believe the best way to prove a null hypothesis is using Chi square testing. what i would like to know is a) is it possible with what i want to do, b) can someone explain how you go about getting an expected number. as i understand it, you need observed numbers and expected numbers.
also if there is something ive missed out here in relation to chi squared, please feel free to fill me in :)

thanks

You haven't really defined your problem and some of the terms you use can have rather vague meanings but I can try and help.

What are these questions? True or False? Multiple choice? Essay questions?

What do you mean by Null hypothesis? That there will be no correlation between the answers to different questions or that there will be no correlation difference between the answers the different groups give?


The actual Chi2 probability is very straightforward once your problem is well defined but with the information given its hard to help.
