Interpretive Summary:

Technical Abstract: In this book chapter, information on how field experiments in invertebrate pathology are designed and the data collected, analyzed, and interpreted is presented. The practical and statistical issues that need to be considered and the rationale and assumptions behind different designs or procedures are given, rather than the nuts-and-bolts of specific types of analysis. Statistical approaches for comparing two or more treatments and determining and comparing trends are presented. Issues dealing with experimental design are discussed; including the selection of experimental treatments, methods of sampling, selection of experimental units, and determining the amount of replication. A number of experimental designs are presented and some of the issues associated with their use are discussed. Some approaches to data analysis and presentation are also included, including dealing with missing data and outliers.
