Dr Jonathan Cardoso-Silva COL.1.03

This course is available on the BSc in Politics and Data Science. This course is available as an outside option to students on other programmes where regulations permit and to General Course students.

While this course is not capped and, in principle, any student who requests a place is likely to be given one, restrictions might need to be imposed if the demand is too high.

Material from the previous year can be found on the course's dedicated public webpage: https://lse-dsi.github.io/DS105/.

The main goal of this course is to teach students how to collect and handle 'real data' in a hands-on manner. The first few weeks of the course will cover theoretical concepts through traditional lectures with slides, but then the format will shift to a more practical approach. Live coding demonstrations will be used to guide students through the material, which can be followed in real-time on their laptops. Python will be the primary programming language used in staff-led lectures and classes, but students are also permitted to use R for their assignments if they prefer.

An important note on programming: While programming is not strictly required for this course, basic programming knowledge, preferably in Python or R, is highly recommended. Students should be comfortable creating and updating variables, creating simple functions, and using flow control expressions like if-else statements, for and while loops, etc. Those who are new to coding may find the course challenging, and we encourage them to consider the Winter iteration of the course, DS105W. This will provide additional time to improve their programming skills. We recommend that students with limited programming experience explore courses such as ST101, Digital Skills Lab workshops or the pre-sessional courses listed on the DS105 Moodle page.

In terms of content, the learning objectives of this course are to:

• Understand the basic structure of data types and common data formats.
• Show familiarity with international standards for common data types.
• Manage a typical data acquisition, cleaning, structuring, and analysis workflow using practical examples.
• Clean data and diagnose common problems involved in data corruption and how to fix them.
• Understand the concept and fundamentals of databases.
• Link data from various sources.
• Use the collaboration and version control system GitHub, based on the git version control system.
• Markup Language and the Markdown format for formatting documents and web pages.
• Create and maintain simple websites using HTML and CSS.
• Use APIs to send and retrieve data from Internet sources.

Note that this course introduces basic concepts of databases, but it is not a hands-on course on their use. If you are interested in learning more about databases, we recommend that you consider taking ST207 Databases, which covers the topic in more detail.

16 hours and 40 minutes of lectures and 13 hours and 30 minutes of classes in the AT.

Reading Week in Week 6.

In the initial sessions, students will work on weekly and structured problem sets in the staff-led class sessions. Examples of exercises involve navigating the terminal on the computer, accessing computer servers, writing code to scrape and pre-process data from the Web, and setting up GitHub.

Later on, students will be expected to work on their group projects in the staff-led class sessions.

Coursework (60%, 1000 words) and group project (40%) in the WT.

The coursework will involve three individual programming assignments.

The group project will include progress presentations and a final public report. The final part of the group project will involve creating a data-based public website that will be published on GitHub. The deadline for the final project will be set for the early Winter Term.
