13. Study design and choosing a statistical test - The BMJ
In terms of selecting a statistical test, the most important question is “what is the main study hypothesis?” In some cases there is no hypothesis; the investigator just wants to “see what is there”.
Focus on Data: Statistical Design of Experiments and Sample Size ...
Statistical guidelines are provided outlining good principles of experimental design, including replication, randomization, blocking or grouping of subjects, multifactorial design, and sequential approach to experimentation.
The selection of a statistical method and its appropriateness depend on the questions or information sought, the validity of theoretical assumptions, the adequacy of the sampling design, and the type, quantity, and quality of the observations.
This book is about the statistical principles behind the design of effective experiments and focuses on the practical needs of applied statisticians and experimenters engaged in design, implementation and analysis.
Statistical Design - SpringerLink
Statistical design is one of the fundamentals of our subject, being at the core of the growth of statistics during the previous century. Design played a key role in agricultural statistics and set down principles of good practic, principles that still apply today.
Statistical Design and Analysis of Experiments is intended to be a practitioner’s guide to statistical methods for designing and analyzing experiments. The topics selected for inclusion in this book represent statistical techniques that we feel are most useful to experimenters and data analysts who must either collect, analyze, or interpret data.
This book takes the reader through the entire research process: choosing a question, designing a study, collecting the data, using univariate, bivariate and multivariable analysis, and publishing the results. It does so by using plain language rather than …
