Hello All, I am new to R and statistics.Pardon me if this a trivial question. Can the Marascuilo procedure be applied to a 2 x c contingency table with c equal to 2 ? My understanding is that it is used to compare proportion between two variables and see which pairs are more significant to make the null hypothesis be rejected. Is this understanding correct? Also, what post hoc tests can be used on categorical data using R. Can someone lead me to examples or links. I am interested in finding once the Null Hypothesis is rejected then which of the categories are influencing. Null hypothesis (Ho) could be like - old ppl do not do more research before visiting a doctor.once Ho is rejected I want to find if out of old or young who actually do more research. I am currently on a project on hypothesis testing , market survey categorical data based designed on a 7 scale lickert analysis. Thanks in Advance. - Harmeet
Your question is about statistics, not R. Do read the Posting Guide to inform
you for future questions. Meanwhile, you should probably go to

If this matters -- i.e it is not merely a matter of homework or thesis work -- I suggest you speak with a local statistical expert, as your statistical understanding appears to be too confused to get much help from online forums.
