"This short presentation is intended to provide a quick introduction to significance (chi-squared) testing. It is designed to allow students to quickly get to the point where they can analyse real data that they have contributed to. It is not meant to be a comprehensive study of this topic, which is left to the textbooks and other online sources. This presentation can also be used as a revision resource for those who have already studied this topic in more detail.

One notion that should be stressed is that of having a ‘feel’ for the data and making a guess at the result before the calculator is used. "
