Module description

This module is designed to provide students with an introduction to the statistical principles used in data science and their applications, and the use of practical programming packages for data analysis and visualisation.

Students will also study data analysis techniques, including causal inference, correlation, classification, regression, and clustering.

Module aims

The aim of this module is to familiarise students with the main concepts, techniques and challenges involved in data science applications and to provide students with practical programming experience.

Module learning outcomes

After completing this module, students will be expected to be able to:

1. Demonstrate a critical understanding of the fundamental concepts of statistical principles
2. Demonstrate a critical understanding of the basics of the Python data science stack
3. Visualise and present models and data interpretations formally
4. Demonstrate knowledge of a range of established data analysis techniques
5. Apply data analysis techniques to analyse complex data
