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.

For this example at a = .05, we have two decision rules: 1. If observed X* is less
than X%73 (59.0 in this example), we have evidence of a clumped pattern. 2. If
observed X* is greater than x^2s (99.6 in this example), we have evidence of a ...
8.1.1 Estimation of Parameters In simple random sampling, one or more
characteristics are measured on each experimental unit. For example, in quadrat
sampling you might count the number of individuals of Solidago spp. and the
number of ...
As an example, suppose that you have measured the survival time of rainbow
trout fry exposed to the effluent from a coal-processing plant. If the plant is
operating correctly, you know from previous laboratory toxicity studies that mean
