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.

0.12348 5.2.4 Variable-Area Transect Method This method is a combination of
distance and quadrat methods and was first suggested by Parker (1979). A fixed-
width strip is searched from a random point until the nth individual is located in
Step 3. Estimate or guess the unknown parameters of the population that you
need to solve the equation. In this simple case we need to have an estimate of s,
the standard deviation of the variable measured. How can we get an estimate of
15.3 CENTRAL TREND LINES IN REGRESSION Linear regression theory, as
developed in standard statistics texts, applies to the situation in which one
independent variable (X) is used to predict the value of a dependent variable (Y).
