Course Overview
The Postgraduate Certificate in Data Science is a 30 ECTS foundation programme designed for professionals and graduates seeking to build core competencies in data-driven decision-making. It covers programming, exploratory data analysis, statistical inference, and includes a focused analytics project.
Through interactive workshops, real-world case studies, and hands-on exercises, participants learn to interpret and communicate insights from diverse datasets, developing practical skills applicable across industries. The certificate also offers a direct pathway to the Postgraduate Diploma or MSc in Data Science.
Course modules
Module 1 — Exploratory Data Analysis
Most industry analysis starts with exploratory data analysis and a thorough study of this will help you to perform data health checks and provide initial business insights. You will gain a sound understanding of Python and R programming, descriptive statistics, data management and data visualisation. You will also learn SQL for big data pre-processing and prepare data for big data analytics.
- Programming in Python, R and SQL
- Data management
- Measures of central tendency and variation
- Data visualisation
Module 2 — Statistical Inference
Statistical inference is the process of drawing inferences or conclusions from data using statistical techniques. In this module you will cover sampling, statistical distribution, hypothesis testing, and variance analysis, and use R code to carry out various statistical tests and draw inferences from their output.
- Principles of statistical inference
- Parametric tests
- Non-parametric tests
- Analysis of variance (ANOVA)
Module 3 — Fundamentals of Predictive Modelling
This module introduces predictive modelling and provides a foundation for more advanced methods and machine learning. You'll gain an understanding of the general approach to predictive modelling and then build simple and multiple linear regression models in Python and R and apply these in a range of contexts.
- Predictive modelling principles
- Linear regression models
- Model validation
- Python and R packages for predictive modelling
Module 4 — Advanced Predictive Modelling
In this module you are introduced to model development for categorical dependent variables. Binary dependent variables are encountered in many domains such as risk management, marketing, and clinical research, and this module covers detailed model building processes. Multinomial and ordinal logistic regression are also covered.
- Logistic regression models
- Survival analysis
- Cox regression
- Poisson regression
Module 5 — Data Science in Practice
The Data Science in Practice module provides you with an opportunity to apply your knowledge through project work. You will select a project from a specific domain and appropriately apply exploratory data analysis, statistical methods and select appropriate predictive modelling techniques. This module also develops your scientific communication skills through the preparation of project reports and presentations.
- Presentation and communication skills
- Synthesis of data science knowledge
- Application to real-world data and scenarios

Admission
The programme welcomes applicants from a range of backgrounds and offers two routes: an academic route for those with a suitable qualification, and a non-academic route for candidates with relevant professional experience.
Academic entry route
For applicants with a suitable academic qualification.
- Honours degree
A 2.2 honours degree (or international equivalent) in a numerate or analytical discipline: Mathematics, Statistics, Computer Science, Engineering, Physics, Sciences, Economics or Business Studies with a quantitative focus.
- Alternative qualifications
Alternative qualifications demonstrating sufficient quantitative or analytical skills are also considered.
Non-academic entry route
For candidates with relevant professional experience or non-degree qualifications.
- Professional experience
At least four years of relevant professional experience, recognised as prior learning (RPL).
- Provisional admission
Join the study track with provisional status under performance-based admission (PBA).
- Full admission
Achieve a GPA of 90% or higher in the first two modules.
- Documents
CV, educational certificates and employer references; supplementary registration fees apply.
English language. IELTS 6.5 or higher, or equivalent, for non-native speakers.

Questions
What are some potential job roles or career pathways after completing the Postgraduate Certificate (PGC) in Data Science?
The certificate builds the core skills used in data-driven decision-making across industries: programming, exploratory data analysis, statistical inference and predictive modelling. It is also a direct pathway to the Postgraduate Diploma or MSc in Data Science for those aiming at more advanced roles.
Does this course offer upskilling opportunities for professionals already in the field?
Yes. The certificate is designed for professionals as well as graduates who want to build core competencies in data-driven decision-making, and every live class is recorded so you can study around work.
