Always label your answers (e.g., "individuals/year" or "bars").

The AP Biology formula sheet is a two-page document provided during the exam. It focuses on statistics, probability, and specific biological equations. You don’t need to memorize these formulas, but you must know and how to apply them. 📊 Statistics and Probability

): Determines if the difference between observed and expected results is due to chance or a specific variable (e.g., genetics). ap biology formula sheet

The back of the sheet has metric conversions and pH = -log[H⁺] — easy points if you don’t freeze up.
