AP BIO EQUATIONS AND FORMULAS REVIEW SHEET #1 Formulas: Mode = value that occurs most frequently in a data set Median = middle value that separates the greater and lesser halves of a data set Mean = sum of all data points divided by the number of data points Range = value obtained by subtracting the smallest observation (sample minimum) from the greatest (sample maximum) Standard Deviation = where = mean and n = size of the sample Example problem: One of the lab groups collected the following data for the heights (in cm) of their Wisconsin Fast Plants: 5.4 7.2 4.9 9.3 7.2 8.1 8.5 5.4 7.8 10.2 Find the mode, median, mean, and range. Show your work where necessary. 4.9 5.4 5.4 7.2 7.2 7.8 8.1 8.5 9.3 10.2 Mode:__5.4, 7.2 ___

AP BIOLOGY SEMESTER 1 EXAM REVIEW UNIT 1: MECHANISMS OF EVOLUTION Darwinian Evolution Evidence Paleontology, biogeography, embryology, comparative anatomy, homologous structures, analogous structures, vestigial structures, molecular biology, artificial selection Natural Selection Over-production of offspring, inherited variation, competition, adaptations, fitness, reproductive success of advantageous traits Stabilizing selection (human birth weight, extremes selected against - too small won?t survive, too big difficult birth), directional selection (pesticide resistance, peppered moth), disruptive selective (opposite of stabilizing), sexual selection (male competition, female choice)
