Statistical procedures for agricultural research - PDF Free DownloadIn this chapter, information on how field experiments in invertebrate pathology are designed and the data collected, analyzed, and interpreted is presented. The approach will be to present this information in a step-by-step fashion that, hopefully, will emphasize the logical framework for designing and analyzing experiments. The practical and statistical issues that need to be considered along the way and the rationale and assumptions behind different designs or procedures will be given, rather than the nuts-andbolts of specific types of analysis.
