Graduate Certificate in Theoretical Statistics and Probability

Course code: S04

This certificate teaches the theory that underpins statistical inference and probability, equipping you to understand the assumptions and limitations of a range of statistical models. You’ll gain a thorough understanding of the theory you need as a professional statistician. Study the mathematical theory underlying methods and concepts used in practical statistical analyses while learning to develop probability models and investigate their properties.

  • Cover analytical approaches, classical and Bayesian statistics and the underpinning mathematical theory
  • Learn about distribution theory and a range of probabilistic models
  • Understand the theory behind statistical inference
  • Gain the skills to comment critically on analyses and model choices

How much will it cost in England?

We believe cost shouldn’t be a barrier to achieving your potential. That’s why we work hard to keep the cost of study as low as possible and have a wide range of flexible ways to pay to help spread the cost.

  • A qualification comprises a series of modules, each with an individual fee. Added together, they give you the total cost.
  • Fees are paid on a module-by-module basis – you won't have to pay for the whole of your qualification up front.
  • Our current fee for 60 credits is £3,892*.
  • Our current fee for 120 credits, which is equivalent to a year’s full-time study, is £7,784*.
  • At current prices, the total cost of your qualification would be £3,892*.

*The fee information provided here is valid for modules starting before 31 July 2026. Fees typically increase annually. In England, fees are subject to the part-time fee limit, as set out in section 5 of the University's Fee Rules.

Additional costs

Study costs

There may be extra costs on top of the tuition fee, such as set books, a computer and internet access.

If your income is not more than £25,000 or you receive a qualifying benefit, you might be eligible for help with some of these costs after you start studying.


How will I study this course?

With our unique approach to distance learning, you can study from home, work or on the move.

You’ll have some assessment deadlines to meet, but otherwise, you’ll be free to study at the times that suit you, fitting your learning around work, family, and social life.

For each of your modules, you’ll use either just online resources or a mix of online and printed materials.

Each module you study will have a module website with

  • a week-by-week study planner, giving you a step-by-step guide through your studies
  • course materials such as reading, videos, recordings, and self-assessed activities
  • module forums for discussions and collaborative activities with other students
  • details of each assignment and their due dates
  • a tutorial booking system, online tutorial rooms, and your tutor’s contact details
  • online versions of some printed module materials and resources.

If you have additional needs, we can also provide most module materials in alternative formats. Find out more about materials on our accessibility webpage.

See how our module websites work.

Tutor support

Student, Joe, talks about balancing working at the NHS and studying with the OU and how he has the best of both worlds.

You’ll have a tutor for each module, who will introduce themselves before the module begins.

Throughout the module, they will:

  • mark your assignments and give feedback to help you improve
  • guide you to learning resources
  • support you, whether with general study skills or help with a specific topic.

Tutorials

Tutorials usually take place online, and they’re always optional.

Online tutorials are live presentations with module tutors in dedicated online tutorial rooms and are sometimes recorded.

Assessment

Our assessments are all designed to reinforce your learning and help you show your understanding of the topics. The mix of assessment methods will vary between modules.

Computer-Marked Assignments

  • Usually, a series of online, multiple-choice questions.

Tutor-Marked Assignments

  • You’ll have a number of these throughout each module, each with a submission deadline.
  • They can be made up of essays, questions, experiments or something else to test your understanding of what you have learned.
  • Your tutor will mark and return them to you with detailed feedback.

End-of-Module Assessments

  • The final, marked piece of work on most modules.
  • Modules with an end-of-module assessment won’t usually have an exam.

Exams

  • Some modules end with an exam. You’ll be given time to revise and prepare.
  • You’ll be given your exam date at least 5 months in advance.
  • Most exams take place remotely, and you will complete them at home or at an alternative location.
  • If a module has an in-person exam (that you must take at one of our exam centres) or is invigilated online, we’ll make this clear in the module description.

Progressing to a point where I felt more comfortable writing my assignments, and having my scores reflecting that, made me quite happy because it showed the hard work was being rewarded.

Skills for career development

Statistics is important for everyday problem solving and decision making. This certificate will equip you with the important mathematical underpinning for statistical methods, so you’ll have the theoretical knowledge to prepare you for work as a statistician. Applications of probability theory include patterns of events that occur in both time, such as earthquakes; and space, for example the occurrence of a species of plant; together with areas such as genetics and changes in stock market prices.

Career relevance

Qualified statisticians are in great demand in the workplace – in particular, those with the theoretical underpinning to ensure the correct analysis is undertaken are in short supply in all areas, including the sciences, economics, education, engineering, environmental studies, finance, government statistics, logistics, medicine and pharmaceuticals.

Exploring your options

Once you register with us (and for up to three years after you finish your studies), you’ll have full access to our careers service for a wide range of information and advice, including: online forums, website, interview simulation and vacancy service, as well as the option to email or speak to a careers adviser. Some areas of the careers service website are available for you to see now, including help with looking for and applying for jobs. You can also read more general information about how OU study enhances your career.
