This coherent text translates the methods of statisticians into "ecological English" so that students may readily apply these methods to the real world. Ecological Methodology, Second Edition provides a balance of material on animal and plant populations. It teaches students of ecology how to design the most efficient tests in order to obtain maximum precision with minimal work. The first part of the text focuses on biological and technical issues in statistical methodology. Students learn about advances that have been made in designing better sampling devices, along with the techniques and equipment used for sampling. The second part deals with creating solid statistical design, and presents all methods that are well-known to statisticians in a language and context that students will easily understand.

Some types of probability sampling are more convenient than others, and simple
random sampling is one. Simple random sampling is defined as follows: 1. A
statistical population is defined that consists of N sampling units; 2. We select n ...
Adaptive sampling is often much more efficient for a given amount of effort than
the conventional random sampling ... an initial sample of quadrats selected by
simple random sampling with replacement, or simple random sampling without ...
Simple random sampling is the easiest and most common sampling design. Each
possible sample unit must have an equal chance of being selected to obtain a
random sample. All the formulas of statistics are based on random sampling, and
