Northeastern Tiger Beetles: A Field Guide to Tiger Beetles of New England and Eastern Canada is the first book to draw together information about adult and larvae of tiger beetles of New England and Eastern Canada. Details are provided about key characteristics of adults and larvae; habitat; range; and life history information of the various species, including notes on conservation status of rare or endangered species.

This book is aimed directly at students of geography, particularly those who lack confidence in manipulating numbers. The aim is not to teach the mathematics behind statistical tests, but to focus on the logic, so that students can choose the most appropriate tests, apply them in the most convenient way and make sense of the results. Introductory chapters explain how to use statistical methods and then the tests are arranged according to the type of data that they require. Diagrams are used to guide students toward the most appropriate tests. The focus is on nonparametric methods that make very few assumptions and are appropriate for the kinds of data that many students will collect. Parametric methods, including Student¿s t-tests, correlation and regression are also covered.
