These are interactive tutorials created using learnr. They are two practicals (3 hours each) about statistical modelling and experimental design. Functional responses are used as the example model.
- Part 1 - Constructing a statistical model based on functional responses and predator-prey interactions. Design and conduct an experiment (Holling's disc equation experiment)
- Part 2 - Analyse data collected in Part 1 using multiple linear regression. Visualise the data graphically.
These teaching materials are developed for BYU22S01 Statistics and Computation, Trinity College Dublin, Ireland and provided under a CC0 license. Contact Dr Jacinta Kong for queries: Email.
The tutorials require R version 4.0 or higher.
