Module description

The use of Bayesian statistics is increasingly common in psychology. This course aims to give a broad introduction to these tools, and how to use R (a popular, open source statistical software package) to analyse and visualise data. It will also give you an overview of how the human brain deals with uncertainty and probabilities, and how the media often misrepresents statistical issues. Throughout the course, you will gain familiarity with working with large datasets, identifying patterns and presenting data. These skills are useful not only for further postgraduate study, but also are increasingly valuable in graduate jobs outside academia.

Module aims

This module will provide students with an opportunity to develop advanced research skills. Students who take this module will learn how Bayesian methods allow us to characterise uncertainty, both in empirical data and our beliefs and perception about the world. They will also gain experience in thinking critically about statistics, and learn about how the human brain deals with probabilities and uncertainty.

Module learning outcomes

At the end of the module, students should:
1. be able to do basic data processing in R
2. create appropriate and engaging data visualisations
3. understand the differences between Bayesian and frequentist approaches to data analysis
4. be able to fit Bayesian linear models to data, visualise the results, and make new predictions
5. give examples of when our brains can handle uncertainty, and when they can’t

Learning outcome 1, 2, and 4 will be assessed by regular homework assignments throughout the term, and an open-book computer test at the end of term. Outcomes 3 and 5 will be assessed in an exam.

Module information

Lectures start on the hour. Please arrive promptly to avoid disrupting the class. Please ask questions during class if there is anything that is unclear. The drop-in support sessions are optional, but you are encouraged to attend. This course requires using the programming language R. The course textbook is Statistical Rethinking (Mc Elreath, 2016).

Learning and teaching methods

This module is primarily taught as a reading course, and students are expected to read a chapter each week from the course textbook. Voluntary support sessions (online and/or lab based) will be provided each week and students are encouraged to attend and ask any questions they may. In addition, there are four compulsory lectures throughout the term.

Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
