Data Capture and Preparations G (11520.1)

Level: Graduate Level
Credit Points: 3
HECS Bands: 2
Faculty: Faculty of Science and Technology
Discipline: Academic Program Area - Technology



A score skill of a data scientist is to capture, extract and clean data. Real world data often come from various data sources, in various formats and are unorganized. This unit introduces students to the concepts and techniques a data scientist employs in the early stages of data analysis process. This unit will provide hands-on experience in capturing data from sensors, collecting data from public information as well as working with existing data sets using real-world examples. Such data may be temporal or spatial, ordinal or categorical, embedded in documents or files. Students will learn how to import and clean the data, which usually involves multiple, often complicated, steps to convert data from its raw format to a clean format that greatly facilitates the later stages of the data analysis. This is known as data wrangling.

Learning Outcomes

After successful completion of this unit, students will be able to:

1. Work with sensors for capturing data;

2. Choose and apply appropriate techniques for capturing data from existing sources;

3. Import data into R;

4. Convert data from one format to another one in R;

5. Employ suitable techniques for tidying data; and

6. Develop a sound understanding of text mining methods in R.
