This project aims at understanding the differences between the size of three species of penguins (Adelie, Chinstrap and Gentoo) observed in the Palmer Archipelago, Antarctica. The data was collected by Dr Kristen Gorman between 2007 and 2009.

• Kristen Gorman: data collection

• Olivia Angelin-Bonnet: data analysis

The raw penguins measurements, stored in the penguins_raw.csv file, were downloaded from the palmerpenguins package.
