Next week: Combining continuous and categorical variables
Designing experiments - keeping it simple Last words… Experiments should be designed and not just happen Think about reducing error variation and replication: enough separate datapoints randomisation: avoid bias and give separateness blocking: managing the unavoidable error variation The statistical ideas we’ve been learning so far in the course help us to understand experimental design and analysis Next week: Combining continuous and categorical variables Read Chapter 6
