18.2. Learning Objectives

Conceptual

After this week, you should be able to:

• Understand the difference between observational data and an experiment.

• Understand the idea of a ‘natural experiment’ and how these are similar and different to other experiments.

• Understand exactly how an experiment helps to establish causality.

• Understand the limits of observational data for establishing causality.

These points will be covered in the lecture.

Python Skills

There is no new Python code this week. In your tutorial, you will be consolidating your skills and preparing for the exam by doing a practice exam question.
