Penguins! They’re fluffy! They’re cuddly! Whats not to like?
The Palmer Penguins dataset is a collection of biological measurements for three penguin species found in the Palmer Archipelago, Antarctica. It has become the gold standard for teaching data science.
Dataset Structure
The curated version of the dataset contains 344 observations across 8 variables:
| Variable | Type | Description |
|---|---|---|
| Species | Categorical | Adélie, Chinstrap, or Gentoo |
| Island | Categorical | Biscoe, Dream, or Torgersen |
| Bill Length | Numerical () | Length of the upper ridge of the beak (culmen) |
| Bill Depth | Numerical () | Vertical thickness of the beak |
| Flipper Length | Numerical () | Length of the penguin’s flipper |
| Body Mass | Numerical () | Total weight of the penguin |
| Sex | Categorical | Male or Female |
| Year | Numerical | Year of study (2007, 2008, or 2009) |
Lab Questions
- What is the relationship between flipper_length_mm and body_mass_g?
- Create a linear AI model that takes in flipper_length_mm and body_mass_g as inputs, and predicts the gender of the penguins.
- Which is a better predictor of gender? year or bill_length?
Dataset Source
The data was collected by Dr. Kristen Gorman and the Palmer Station, Antarctica LTER (Long Term Ecological Research) Program. It was originally published as part of a 2014 study on the foraging behavior and environmental variability of Antarctic penguins. Link
