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.

Statisticians always assume that a sample is taken according to the principles of
probability sampling, as follows: 1. Define a set of distinct samples S1, S2, S3 ...
in which certain specific sampling units are assigned to S1, some to S2, and so ...
There are two basic choices that you must make in selecting a multistage
sampling design model: whether to choose the primary sampling units with equal
probability or with probability proportional to size (PPS). For example, in Figure
