Statistics for Humanities is a new open resource developed by my former University of Southampton colleague, John Canning. The content has been created to help Humanities undergraduates get to grips with some of the basics of understanding and using statistics in their work. It also provides detailed support around collecting, managing and analysing quantitative data. John has used lots of examples for Humanities subjects to illustrate particular points.
Statistics for Humanities is a really helpful, readable resource and I would recommend it to any Humanities academic who is looking for an introduction to quantitative work.
