Analyst Data Description (and Possible Prediction Plan):
--------------------------------------------------------
A row represents: one penguin
A target we might predict: body_mass_g
A feature that might help: bill_length_mm
Why the feature might help:
A bigger penguin probably has both a longer bill and more mass,
so bill length might help predict body mass.
That is, a longer bill may indicate a larger body mass.
