Data

A brief description of your dataset including its provenance (e.g., “The data were originally collected as part of Gorman, Williams, and Fraser (2014) and distributed via Community (2024) and Horst, Hill, and Gorman (2020).”), dimensions, etc. as well as the reason why you chose this dataset.

Make sure to load the data and use inline code for some of this information, as exemplified below.

penguins <- read_csv("data/penguins.csv")

Rows: 344 Columns: 8
── Column specification ────────────────────────────────────────────────────────
Delimiter: ","
chr (3): species, island, sex
dbl (5): bill_length_mm, bill_depth_mm, flipper_length_mm, body_mass_g, year

ℹ Use `spec()` to retrieve the full column specification for this data.
ℹ Specify the column types or set `show_col_types = FALSE` to quiet this message.

Questions

The two questions you want to answer.

Analysis plan

A plan for answering each of the questions including the variables involved, variables to be created (if any), external data to be merged in (if any). This should also include a feasibility assessment on how the data you have can be used to answer the questions you stated.
