- Research questions: How to ask well-defined research questions
- Populations: How to infer properties of populations from samples
- Manipulative experiments: Sampling design to infer causal relationships
- Randomisation: How to collect independent samples for valid inference
- Control: Importance of comparing to a control group, properties of good controls

Practical Component
- How to randomise – Random allocation of subjects to treatments and random sampling in space
- Simple power analysis – How much data do we need to answer the question of interest?
- We will use free online tools and the software packages, Excel and G*Power
