Archaeology Life 101 is how to read any sort of research publication whether it is academic or not. Here is a great lesson on that http://www.slideshare.net/rnja8c/how-to-read-academic-research-beginners-guideIt really breaks down statistics into an easy to understand form. Even if you are a post-processual archaeologists and think statistics are evil the concepts are great.
For example, significance- what is your evidence telling you and how does it compare to other factors. You do not need to use statistics to try to interpret the significance of your findings but you do need to have some comparison to show significance of your findings.
Even if you are not using statistics these concepts are critical for any sort of research or for reaching any sort of conclusion. Sometimes I feel many research publications miss these simple concepts.
