Trending
It combines statistics, computer science, and domain knowledge to understand trends, make predictions, and support decision-making in everything from business and healthcare to sports, social media, climate science, and government.
If you enjoy maths, computing, and problem-solving - and you’re curious about how data influences the world, Data Science could be the right degree for you.
What Is Data Science Like at University?
Data Science sits at the intersection of mathematics, statistics, and computer programming. At university, you’ll learn how to collect, process, analyse and visualise data. You’ll work with large datasets, build predictive models using machine learning, and develop technical skills in programming and data systems.
This is a practical subject, and most courses include a strong focus on real-world applications. You’ll learn how to interpret results clearly, communicate insights effectively, and understand the social, ethical, and legal responsibilities of working with data.
What Will You Study?
While course structures vary, most Data Science degrees cover:
Mathematics and Statistics
You’ll study topics like linear algebra, calculus, probability, and statistical inference. These are key for understanding patterns, making predictions and working with uncertainty.
Programming
Most degrees use languages like Python and R, often alongside SQL for working with databases. You’ll also learn how to write efficient, reliable code to clean and analyse data.
Machine Learning and AI
You’ll learn how to build algorithms that learn from data, from linear regression to neural networks - and how to evaluate and interpret their results.
Data Visualisation
A big part of data science is storytelling. You’ll learn how to use tools like Tableau, matplotlib or Power BI to present insights clearly and persuasively.
Big Data and Databases
You’ll work with large datasets and cloud-based platforms, learning how to store, query and manage data using tools like SQL, Hadoop, or Spark.
Ethics and Governance
You’ll explore the responsibilities that come with working with sensitive information, including data privacy, bias, consent and transparency.
Many courses also include industry projects, group work and a final-year project based on solving a real data challenge.
How Long Does It Take and What Are the Options?
In the UK, Data Science is usually offered as a three-year BSc or a four-year MSci (integrated master’s). In Scotland, BSc degrees last four years and MSci programmes are typically five. Some courses offer an optional year in industry or a year studying abroad.
Data Science is also available as a specialisation within Computer Science, Mathematics, or Artificial Intelligence degrees — so it's worth comparing course structures carefully.
How Will You Be Taught and Assessed?
Teaching includes lectures, programming labs, workshops, and tutorials. You’ll often work on real data problems in group or individual projects. Assessment is usually a mix of coursework, coding assignments, statistics projects, presentations and exams. Practical work is a major part of the learning process.
What A Levels or Subjects Do You Need?
Most universities ask for:
-
Mathematics – essential for almost all Data Science degrees
-
Further Maths – helpful, particularly for competitive or theory-heavy courses
-
Computer Science or Statistics – useful but not always required
Strong analytical and numeracy skills are vital, and experience with coding (even if self-taught) can be a plus when applying.
What Skills Will You Develop?
Studying Data Science will equip you with a wide range of technical and transferable skills, including:
-
Programming and algorithmic thinking
-
Statistical analysis and modelling
-
Data handling and interpretation
-
Communication and data storytelling
-
Critical thinking and problem-solving
-
Teamwork and project planning
-
Awareness of ethics and data governance
These skills are in high demand across nearly every industry.
What Can You Do With a Data Science Degree?
Data Science graduates are well placed for careers in tech, finance, health, business, government and many other sectors. Roles include:
-
Data scientist or data analyst
-
Machine learning engineer
-
Business intelligence analyst
-
Quantitative analyst (quant)
-
AI or NLP developer
-
Statistician or research analyst
-
Product or strategy analyst
-
Data engineer or cloud specialist
-
Consultant in data and analytics
Many graduates work in industries like finance, tech, healthcare, marketing, retail or logistics — or go on to postgraduate study in data science, AI or statistics.
Studying Data Science Abroad
Studying Data Science internationally can give you a global view of data-driven innovation and help you access international career opportunities. Here’s what to expect in different parts of the world:
USA
Data Science is often offered as a major within a Bachelor of Science degree. The US has many universities with strong data science departments and links to industry, particularly in areas like AI, finance, and healthcare analytics. MIT, Stanford, UC Berkeley, and Carnegie Mellon are leaders in the field. Courses typically combine rigorous statistics and computer science training with electives in applied areas.
Canada
Canada is known for its focus on applied learning and offers strong Data Science and Statistics programmes with co-op (work placement) options. The University of Toronto, Waterloo, UBC and McGill are popular choices. Courses often blend technical training with experience in business, health or environmental data.
European Union
Many European countries offer Data Science degrees in English, especially in the Netherlands, Germany and Sweden. TU Eindhoven, TU Munich and Aalto University are top examples. EU courses often take a data ethics-first approach and emphasise sustainability, smart cities, and AI. Bachelor’s degrees are usually three years, often followed by two-year master’s programmes.
Australia
Data Science is growing rapidly in Australia, especially in sectors like agriculture, healthcare and mining. Degrees are usually four years and may be offered as Bachelor of Data Science, Bachelor of IT or within a broader science or commerce degree. UNSW, University of Melbourne and Monash are particularly strong in this area.
New Zealand
New Zealand universities such as the University of Auckland and Victoria University of Wellington offer Data Science as part of Computer Science, Mathematics or Statistics degrees. These programmes are known for strong student support and growing industry connections in environmental, agricultural and business data.
Studying abroad in Data Science can offer exposure to new datasets, tools, research environments and career networks - ideal if you're interested in global data challenges or international business.
Is Data Science the Right Course for You?
If you're curious about patterns in data, enjoy working with numbers and code, and want to use those skills to solve real problems, Data Science could be a great fit. You’ll need to be comfortable with maths, but also interested in learning how to tell stories with data and apply it in a meaningful way.
