Bachelor of Data Science and Decisions
Unlock hidden insights within data.
Unlock hidden insights within data.
Data can help drive social progress as it provides us with answers to complex problems and helps us make informed decisions. How will you use the power of data to change the world?
If you’re thinking about studying data science, you’re probably already aware of its power to shape our world. As billions of devices feed data to central databases, businesses and governments require experts to interpret that data. Data scientists have become one of the most in-demand professionals globally because they have the unique skills to unlock hidden insights within data.
The Bachelor of Data Science and Decisions will prepare you to compile, interpret and act on data in ways that make a big impact. This degree combines training in mathematical methods, statistics, computing and business decision-making with communication skills. You’ll gain the theoretical and practical skills required to enter the field of data analysis, where networking, decision-making, strategic thinking and attention to detail are essential.

The era of Big Data
With quintillion bytes of data generated each day, it’s safe to say that we’re in the era of big data. Social media, the Internet of Things (IoT), machine learning and artificial intelligence are driving trends in data and influencing the role of data scientists. The increasing need for people who can interpret and understand data means that data scientists and analysts are in very high demand across a range of industries.
What does a career in this field look like?
Data science is a multidisciplinary field of study that blends mathematical methods, statistics, computing, business decisions and communication. Data scientists translate user data into insights that help companies understand their audience and personalise their products or services. Uncovering new insights and predicting trends has become vital in the retail, environmental, not-for-profit, IT and professional services sector.
Career opportunities in data science span across many industries from start-ups to established corporations including Coles, AirBnB, Spotify, Netflix and Greenpeace, to name a few. As a data scientist, you might be asked to calculate the price of new products for the market, determine warehouse or retail employee schedules, make predictions of environmental phenomena and model the spread of new diseases.
"My favourite part about the Data Science and Decisions degree was that I could customise it to fit my interests. I got to pick electives from a pool that contains everything from software construction to calculus to economic game theory. This allowed me to follow my passion for mathematics while also building on my newly discovered love of coding, and then get to throw a bit of economics into the mix!"
Jessica Boyle
Consultant, Data Assurance, PwC
"The data science program at UNSW has provided me with a solid foundation in advanced mathematics and computer science, as well as the opportunity to pursue elective courses in physics. Knowledge of these three fields has proven invaluable to my career as they are fundamental to almost every industry."
