Data is the lifeblood of our society. From medicine to government offices, and market research to the environment, the collection and analysis of data is crucial to understanding how to improve, create and guide products and services across the globe.
Harvard Business Review recently described the job of Data Scientist as “the sexiest job of the 21st century”. Data science is about doing some detective work and carrying out the investigations needed to inform important decisions and to predict new trends. Technology is growing and evolving at an incredible speed, and both the rate of growth of data we generate and the devices we use to process it can only increase.
At Essex, we help you to understand how utilising the speed and processing-power of computers can assist in using data to make better decisions. You discover the new methods and the smart, unusual questions needed to make sense of both structured and unstructured data.
Your course balances solid theory with practical application through exploring topics including:
Mathematical skills
Computer science and programming
Statistics and operations research
Artificial intelligence, databases and information retrieval
Ethical issues around the use and processing of data
Specialist skills in the areas of big data, data analytics and data science
A successful career in data science requires you to possess truly interdisciplinary knowledge, so we ensure that you graduate with a wide-ranging yet specialised set of skills in this area. You are taught within our School of Mathematics, Statistics and Actuarial Science and our School of Computer Science and Electronic Engineering.
Data scientists are required in every sector, carrying out statistical analysis or mining data on social media, so our course can open the door to almost any industry, from health, to government, to publishing.
Why we're great.
You join a community of scholars leading the way in technological research and development.
We’re ranked 25th in UK for mathematics (The Guardian University Guide 2025).
You have access to our ultramodern facilities at the STEM Centre that provide real-world experience.
Study abroad
Your education extends beyond the university campus. We support you in expanding your education through offering the opportunity to spend a year or a term studying abroad at one of our partner universities. The four-year version of our degree allows you to spend the third year abroad or employed on a placement abroad, while otherwise remaining identical to the three-year course.
Studying abroad allows you to experience other cultures and languages, to broaden your degree socially and academically, and to demonstrate to employers that you are mature, adaptable, and organised.
If you spend a full year abroad you'll only pay 15% of your usual tuition fee to Essex for that year. You won't pay any tuition fees to your host university
Placement year
Alternatively, you can spend your third year on a placement with an external organisation, learning about a particular sector, company or job role, applying your academic knowledge in a practical working environment, and receiving inspiration for future career pathways. You will be responsible for finding your placement, but with support and guidance provided by both your department and our placements team.
Students are provided with support to secure a placement. Recent placements undertaken by our students have been with ARM, Microsoft, Intel, Nestlé, British Aerospace, and the Rutherford Appleton Laboratory, as well a range of SME software and hardware companies.
If you complete a placement year you'll only pay 20% of your usual tuition fee to Essex for that year.

Our data scientists carefully consider how not to lie, and how not to get lied to with data. Interpreting data correctly is especially important because much of our data science research is applied directly or indirectly to social policies, including health, care and education.
We do practical research with financial data (for example, assessing the risk of collapse of the UK's banking system) as well as theoretical research in financial instruments such as insurance policies or asset portfolios.
We also research how physical processes develop in time and space. Applications of this range from modelling epilepsy to modelling electronic cables.
Our optimisation experts work out how to do the same job with less resource, or how to do more with the same resource.
Specialist facilities
We have a range of laboratories that are exclusively for computer science and electronic engineering students. Three are open 24/7, and you have free access to the labs except when there is a scheduled practical class in progress
All computers run either Windows 10 or are dual boot with Linux
Software includes Java, Prolog, C++, Perl, Mysql, Matlab, DB2, Microsoft Office, Visual Studio, and Project
You have access to CAD tools and simulators for chip design (Xilinx) and computer networks (OPNET)
We also have specialist facilities for research into areas including non-invasive brain-computer interfaces, intelligent environments, robotics, optoelectronics, video, RF and MW, printed circuit milling, and semiconductors
Your future
Demand for skilled graduates in the areas of big data and data science is growing rapidly in both the public and private sector, and there is a predicted shortage of data scientists with the skills to understand and make commercial decisions based on the analysis of big data.
Essex is bridging the gap between academia and business, and we are at the forefront of helping the UK grasp the big data opportunities to get ahead in the global race. Our graduates in data science have been very successful in finding employment in the public sector, consulting, technology, retail, and utilities, while a number have gone on to postgraduate study or research.
Our recent graduates have gone on to work for a wide range of high-profile companies including:
Aviva
AXA
BT
Profusion
EDS
Mondaq
IBM
Royal Bank of Scotland
Accenture
Buck Consultants
Google
Our Schools have a large pool of external contacts, ranging from companies providing robots for the media industry, through vehicle diagnostics, to the transforming of unstructured data to cloud-based multidimensional data cubes, who work with us and our students to provide advice, placements and eventually graduate opportunities.
We also work with our University's Student Development Team to help you find out about further work experience, internships, placements, and voluntary opportunities.
“I knew I wanted to do data science after discovering that it was the perfect subject for people who enjoy both computing and maths. I decided to study at Essex because it was one of the few universities who offered a degree in data science; it was also one of the highest rated universities in the UK. I’m currently enjoying programming the most, purely because I love problem solving, but I’ve enjoyed all of the modules I have studied so far. All of my professors and lecturers are helpful – they devote a lot of their time to us as students."
“I want to travel once I have finished university and therefore work long-distance – which in today’s modern world is definitely possible! Essex partners with a lot of businesses and companies, and gives students opportunities to gain highly useful work experience through a placement year. I think studying at Essex will put me in a great place when I graduate.”
Andreas Loucas, BSc Data Science and Analytics student

Components and modules explained
Components
Components are the blocks of study that make up your course. A component may have a set module which you must study, or a number of modules from which you can choose.
Each component has a status and carries a certain number of credits towards your qualification.
Status
What this means
Core
You must take the set module for this component and you must pass. No failure can be permitted.
Core with Options
You can choose which module to study from the available options for this component but you must pass. No failure can be permitted.
Compulsory
You must take the set module for this component. There may be limited opportunities to continue on the course/be eligible for the qualification if you fail.
Compulsory with Options
You can choose which module to study from the available options for this component. There may be limited opportunities to continue on the course/be eligible for the qualification if you fail.
Optional
You can choose which module to study from the available options for this component. There may be limited opportunities to continue on the course/be eligible for the qualification if you fail.
The modules that are available for you to choose for each component will depend on several factors, including which modules you have chosen for other components, which modules you have completed in previous years of your course, and which term the module is taught in.
Modules
Modules are the individual units of study for your course. Each module has its own set of learning outcomes and assessment criteria and also carries a certain number of credits.
In most cases you will study one module per component, but in some cases you may need to study more than one module. For example, a 30-credit component may comprise of either one 30-credit module, or two 15-credit modules, depending on the options available.
Modules may be taught at different times of the year and by a different department or school to the one your course is primarily based in. You can find this information from the module code. For example, the module code HR100-4-FY means:
HR
100
4
FY
