内容简介
The effective design of scientific experiments is critical to success, yet graduate students receive very little formal training in how to do it. Based on a well-received course taught by the author, Experimental Design for Biologists fills this gap. Experimental Design for Biologists explains how to establish the framework for an experimental project, how to set up a system, design experiments within that system, and how to determine and use the correct set of controls. Separate chapters are devoted to negative controls, positive controls, and other categories of controls that are perhaps less recognized, such as assumption controls and experimentalist controls . Furthermore, there are sections on establishing the experimental system, which include performing critical system controls . Should all experimental plans be hypothesis-driven? Is a question/answer approach more appropriate? What was the hypothesis behind the Human Genome Project? What color is the sky? How does one get to Carnegie Hall? The answers to these kinds of questions can be found in Experimental Design for Biologists. Written in an engaging manner, the book provides compelling lessons in framing an experimental question, establishing a validated system to answer the question, and deriving verifiable models from experimental data. Experimental Design for Biologists is an essential source of theory and practical guidance in designing a research plan.

David (; Biblical Hebrew: דָּוִד, romanized: Dāwīḏ, "beloved one") was, originally, leader of the Tribe of Judah who became the second king of the united Kingdom of Israel, according to the Hebrew Bible and Old Testament. David's reign may have occurred around the 9th century BC, although the timeframe of his reign and geographical boundaries of his kingdom are disputed. Most of what is known of David comes from biblical literature, the historicity of which has been extensively challenged, and
Glass is an amorphous (non-crystalline) solid. Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics. Some common objects made of glass are named after the material, e.g., a "glass" for drinking, "glasses" for vision correction, and a "magnifying glass". Glass is most often formed by rapid cooling (quenching) of the molten form. Some glasses such as volcanic glass are naturally occurrin
