Introduction Welcome to the Handbook of Biological Statistics! This online textbook evolved from a set of notes for my Biological Data Analysis class at the University of Delaware. My main goal in that class is to teach biology students how to choose the appropriate statistical test for a particular experiment, then apply that test and interpret the results. I spend relatively little time on the mathematical basis of the tests; for most biologists, statistics is just a useful tool, like a microscope, and knowing the detailed mathematical basis of a statistical test is as unimportant to most biologists as knowing which kinds of glass were used to make a microscope lens. You may navigate through these pages using the "Previous topic" and "Next topic" links at the top of each page, or you may skip from topic to topic using the links on the left sidebar. I have provided a spreadsheet to perform almost every statistical test. I've also linked to a web page for each test wherever possible. Acknowledgment
AP Biology Lab Manual Resource Center Supplement to the first printing: This Supplement to the First Printing of the lab manual includes updated URLs, corrections, clarifications, sample data tables for Investigation 7, and an updated version of the AP Biology Equations and Formulas appendix. The second printing of the Teacher Manual, available for download below, incorporates these changes. Each PDF below contains the teacher edition (blue banner), followed by the student edition (red banner). The teacher edition and student edition can also be purchased from the College Board Store. You may download the second printing of the full AP Biology Teacher manual (.pdf/19.2MB), which includes the Student manual. Many files on AP Central are saved in Adobe® PDF format.

NDL/FNIC Food Composition Database Home Page NOVA | Rosalind Franklin's Legacy Posted 04.22.03 NOVA When it comes to her place in the discovery of the double helix structure of DNA, Rosalind Franklin has not received fair treatment. Or so maintains Lynne Osman Elkin, a professor of biological sciences at California State University, Hayward, who spends much of her time these days trying to clarify Franklin's significant role in one of the 20th century's greatest scientific achievements. In March 2003, Elkin published a lengthy article on Franklin in Physics Today, and she's hard at work on a biography. In this interview, hear what Elkin has to say about exactly where Franklin stands in her mind—and where Photo 51's creator ought to stand in the history books. With all she did to make Watson and Crick's discovery possible, Rosalind Franklin was essentially "a de facto collaborator," says Lynne Osman Elkin. Within reach NOVA: How close did Franklin actually come to deciphering the structure of DNA? Elkin: She was very close. Picture perfect No. Great potential Cut short

Educational articles, drawings, experiments & PowerPoint presentations by D G Mackean EvoLiteracy – Biology and Science Videos | Evolution Literacy The videos and animations below (180+) follow the chronological order of biology and science topics discussed in my courses for college Biology Majors (each video-/animation-link is connected to additional resources, including weblinks to visuals and/or relevant platforms). I have compiled this information with my BioHonors students, I thank them much for their commitment, support and enthusiasm. Note that, with time, some of the links below might change, I will try to update them as much as possible, but if visitors have observations, suggestions or think that alternative or additional links should be included here, please provide that information in the “comments” section at the end of this page — GPC.

Practical Biology This website is for teachers of biology in schools and colleges. It is a collection of experiments that demonstrate a wide range of biological concepts and processes. Experiments are placed within real-life contexts, and have links to carefully selected further reading. Each experiment also includes information and guidance for technicians. Biology is a practical science. Practical activities are not just motivational and fun: they also enable students to apply and extend their knowledge and understanding of biology in novel investigative situations, which can aid learning and memory, and stimulate interest. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5. Unfortunately, we are unable to respond to questions from teachers, technicians or students on how to use the experiments on this website.
