This wiki was initially started as my personal note of statistical methods commonly used in HCI research, but I decided to make it public and put more content in it because I think this may be useful for some of you (particularly if you use R). I will also put some codes for R, so you can quickly apply the methods to your data. This wiki does not emphasize mathematical aspects of statistics much, and rather tries to provide some intuitions of them. Thus, if you know maths, you may be unhappy about this wiki, but this is the way this wiki exists.
Keep in mind that I am not an expert of statistics. The contents provided here is basically what I learned from my experience of HCI research and by reading different online/offline materials. I always double-check the content before posting, but it still may be not 100% accurate or even wrong. So, use the contents on this website at your discretion. I own no responsibility on any kind of consequences, such as you have done a wrong analysis after reading my wiki or your papers do not get into a conference or a journal, or your adviser doesn't like your analysis.
I also strongly recommend you to get the second opinion on your analysis from other kinds of resource before you really run a test. If you have found any factual errors, please leave your comment. Your comments would be greatly appreciated. You can leave your comments anonymously or with your name (just leave your name at the bottom of your comment). I don't care about the anonymity or non-anonymity (I don't consider you as a coward even if you don't put your name with your comment), but you might be formally acknowledged in this wiki at some point if you leave your name. I will update the content at some point (depending on how serious the problem is and how busy I am...)
In this website, I use R to show some examples of how you can run statistical tests. I assume you can install R in your machine, and you know some basics of how to write a code in R, install packages, etc. You can read the online manual for R. So, please avoid asking how to use R or that kind of stuff in this website. This website is not intended to be a wiki or forum for R.
