Home - 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. 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.

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. Let me know if you find a broken link anywhere on these pages. I have provided a spreadsheet to perform almost every statistical test. Printed version
