R tutorial: Chi squared test

This tutorial will show you how to produce Chi squared tests for nominal data in R. It also covers producing frequency and proportional tables. Write up examples are also included, along with some advice on plotting data.

There is also a brief guide on filtering your data

Data and annotated R code can be found here:

Thank you! The chisq.test itself was giving me some errors about the data types but this worked.

Good video Paul. I have a question that I hope you can help with. When you do the initial ChiSQ test for the whole table you get a significant p value. DOes that mean that that if you were to run the chi sq test on the individual boroughs also wound be significant? Just trying to understand what the test on the whole table versus individual outcomes represents.

When I start the line 'PlotXTabs' I get all the same options as you, excluding 'Chidata', any ideas why that might be?

hello, thank you so much for this great video, I have a small data set and I want the p value. I followed every step here but it wont give the all the stat that you got! I don't know what I am doing wrong :(
