1. Instructions

1. Reports should be handed in as a single PDF file using Blackboard, by noon on the due date. RMarkdown, image, word, zip files, for example, will not be marked.
2. You can work alone or in a group with up to two other people.
3. One person per group should hand in a report. The names and student numbers of all group members must be on the first page.
4. Your answers should combine text and code snippets in R. It is recommended that you use RMarkdown to prepare your reports, since this is typically easier for students, but this is not mandatory.
5. You must explain what you are doing clearly to obtain full marks on each question. You can use comments (which start with #) to annotate your code. Mathematical derivations can be written using LaTeX commands in RMarkdown or on paper, with a photo then appended to the end of the PDF being submitted.
6. This practical counts for 10% of your assessment for Statistics 2.

For example, substantial portions of our understanding of the social sciences and medicine is based on statistical experiments and analysis.
