2021 information for papers will be published in early September.
An introduction to the techniques used to prepare, integrate, manage and visualise complex data using modern software environments. Essential to students needing to manage data in science, business, or humanities.
Data Science skills are in increasing demand in both industry and academia. Being able to effectively and safely manipulate and model data will be a key strategic advantage for future employment. COMP 120 introduces the fundamental concepts of data science to students through practical use of the industry-standard software environment R. You will learn how to program in R, how to effectively manage and manipulate data in R, and be exposed to the “round trip” of data science (Import, Tidy, Transform, Visualise, Model, and Communicate).
Upon completion of COMP 120, you will be well-equipped to embark on your own data acquisition and management in R, as well as be excellently-prepared for other papers that use R for analysis and modelling.

- Paper Structure
This paper covers the following key themes:
- Introduction to programming in R and RStudio
- Importing and tidying data in R (“Data Wrangling”)
- Plotting and visualising data in R
- Data aggregation and summarisation in R
