What Is Data Science?
Data science is the use of data to extract insights. These insights support decision-making across a wide range of industries. Data scientists use statistics, programming, and domain knowledge to analyse patterns and solve problems. The role of data science has expanded rapidly in both business and everyday applications.³

Understanding Data Science in Simple Terms
Data science is the practice of analysing data to extract meaningful insights. It combines statistics, programming, and subject knowledge to interpret patterns and trends. These insights are then used to support decision-making across business, technology, and research.
How Data Science Is Used in Everyday Life
What Is a Data Scientist?
A data scientist works with data to uncover patterns, build models, and generate insights that support decision-making. Their role combines statistical analysis and programming, often including machine learning to predict outcomes or automate processes. Data scientists often work with large and complex datasets and turn raw data into something useful.⁸ Don't confuse data scientists with data analysts, there are similarities, but they're very different roles.
Key Responsibilities of a Data Scientist
Data Scientist vs Data Analyst: What’s the Difference?
Data Scientist
- Builds predictive models and machine learning systems
- Works with large, complex datasets (big data)
- Uses Python, R, and advanced statistical methods
- Focuses on forecasting and automation
- Typically requires stronger programming skills
Data Analyst
- Interprets structured data to identify trends
- Works with dashboards, reports, and visualisations
- Uses tools like Excel, SQL, and BI software
- Focuses on explaining past performance
- Strong emphasis on business insights
Essential Data Scientist Skills
Not just anyone can become a data scientist. There are many skills you'll need. You can't just be good at coding, because you also have to analyse information and communicate results. Professionals must move from raw data to insights that inform real-world decisions.⁷
Technical Skills: Programming, Statistics, and Tools
Data scientists use a range of tools to collect, process, and analyse data. Common programming languages include Python, R, and SQL, while tools like SAS and cloud platforms support large-scale data processing. These technologies allow professionals to build models, automate workflows, and generate insights from complex datasets.
Soft Skills: Communication and Problem Solving
How to Become a Data Scientist
You can't just get hired as a data scientist by telling employers you have the desired skills. Like with all jobs, you need the right skills and experience. It's common for data scientists to study mathematics, computer science, statistics, or a related subject before developing more specialised skills in analysis and modelling. You can also enter the field with shorter courses, technical training, or work-based learning.⁴
Education and Degree Options
Age 18 (Year 1)
Start a relevant degree
Begin a bachelor's degree in data science, computer science, mathematics, or a related field.
Age 19–21 (Years 2–3)
Build core knowledge
