Ap Biology Formula Sheet Page

How fast is a population growing? These formulas tell the story: Rate (

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

You are allowed a 4-function, scientific, or graphing calculator. Use it to double-check your Chi-square math!

log x = y → 10^y = x ln x = y → e^y = x ap biology formula sheet

): Simply the change in "something" over the change in time.

These formulas help you determine if your results (like the number of purple vs. white flowers) happened by chance or because of a biological law. Used to compare observed results with expected results. The Key: If your calculated χ2chi squared How fast is a population growing

The sheet includes a Chi-Square table; remember that Degrees of Freedom is usually If you'd like to dive deeper, let me know:

This is the "gold standard" for evolution questions. It describes a population that isn't evolving. : Deals with (A and a). : Deals with individuals/genotypes (AA, Aa, and aa). Pro Tip: Always find q2q squared

Used for "either/or" mutually exclusive events. Multiplication Rule: Used for "and" independent events. 🧬 Evolution and Genetics These formulas help track how populations change over time. Hardy-Weinberg Equations: (Allele frequencies) (Genotype frequencies) You don’t need to memorize these formulas, but

You’ve probably seen the and thought: “Wait… math in bio?”

(the frequency of the homozygous recessive phenotype) first. Once you have q2q squared , take the square root to find , and the rest of the puzzle falls into place. 4. Ecological and Population Growth
