Bachelor of Science (Major in Decision Analytics) (BSc)

 Aims and Features

The world is now experiencing a proliferation of digitized data whose volume, variety and velocity continue to reach unprecedented levels. Capturing and analyzing data have tremendously influenced how decisions are made and how resources are allocated in various fields, as the accuracy of data processing can affect the results variably.

Not content with mere accumulation of colossal amount of data in multiple data stores and abundant formats, Decision Analytics enables us to examine, translate and classify the data, uncover hidden patterns and unknown correlations, and, most importantly, pinpoint precisely the most critical areas and the implications suggested by the data. Useful information can then be extracted and used as a strategic part of critical decision-making or resource allocation for the best course of action at minimal risk.

Decision Analytics involves extensive analysis of data, which may be structured or unstructured, using different techniques and tools including but not limited to statistical analysis, data mining and data visualization, computer programming, data structuring, mathematical and statistical modelling and implementation of database systems.

With 'Big Data' being one of the most popular topics of conversation in town, the Major in Decision Analytics (Programme Code: 6901) will provide a comprehensive study for students to equip themselves with the necessary expertise in leveraging and managing big data in real time and to acquire a competitive advantage in becoming vital assets of any organisations which need to make decisions.

Comprised of a wide range of Statistics, Computer Science and Mathematics courses to give a well-balanced curriculum in terms of interdisciplinarity and comprehensiveness, the Major in Decision Analytics is ideal for students whose interest in statistics, mathematics and computer science crosses over disciplinary divides and combines high-level analytical skills in decision-making and problem-solving. It is also an ideal second major for those pursuing degrees in science, social sciences, information systems, business and quantitative finance.
