DATA SCIENCE PRINCIPLES AND PRACTICES - 2022/3

Module code: COMM054

Module Overview

The module provides for coverage of a variety of statistical methods, including descriptive statistics and validating formulated hypotheses, as well as predictive analytics. The computational foundations and methods of importance to data science are also covered, along with consideration for relevant supporting software and tools, and the need for data science governance.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate the ability to critically appreciate and apply statistical methods and (predictive) analytics. Thus, the summative assessment for this module consists of:

• A class test, mid-term, addressing LOs 1-4 in respect to module content covered up to a week prior to the test.

• An examination, evaluating all LOs with respect to both principles and practices of Data Science Principles and Practices Formative assessment Students will be guided to work on weekly tasks through lab exercises, the solutions to which will provide for feedback on understanding and practice, which will feed forward into the class test and the exam.

Module aims

  • This module aims to introduce students to the necessary background material in statistics and probability that underlie modern data science and machine learning, with applications to real world problems, and to provide students with practical experience in working with these tools.

Methods of Teaching / Learning

The learning and teaching strategy is designed to provide students with the knowledge, skills, and practical experience covering the module aims and learning outcomes.

The learning and teaching methods include: 11 teaching weeks with each week comprising:

2 hours of lectures, to convey and discuss the key concepts and principles

1 hour tutorial, to discuss the material covered in lectures

1 hour lab session, to put key concepts and principles into practice.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
