Throughout the rest of this course we will use the Palmer Penguins dataset, collected by Dr. Kristen Gorman at Palmer Station, Antarctica.
Gorman KB, Williams TD, Fraser WR (2014) Ecological Sexual Dimorphism and Environmental Variability within a Community of Antarctic Penguins (Genus Pygoscelis). PLoS ONE 9(3): e90081. doi:10.1371/journal.pone.0090081
It contains measurements for 344 penguins belonging to three species:
The features available are:
| Feature | Type | Description |
|---|---|---|
bill_length_mm |
Numeric | Length of the bill in millimetres |
bill_depth_mm |
Numeric | Depth (height) of the bill in millimetres |
flipper_length_mm |
Numeric | Flipper length in millimetres |
body_mass_g |
Numeric | Body mass in grams |
island |
Categorical | Biscoe, Dream, or Torgersen |
sex |
Categorical | Male or Female |
We can load the dataset directly from the Python seaborn library.
# Load libraries
import seaborn as sns
# Load the dataset
penguins = sns.load_dataset("penguins")
# Show the first few rows
