Part of the Health Informatics book series (HI)

Abstract

This chapter provides an overview of different types of evaluation studies and their advantages and disadvantages. The studies that are reviewed range from naturalistic observations to controlled experiments. They differ in the amount of intervention by researchers and the degree to which the environment is controlled. For each, examples from the literature are included as illustrations.

Since this book focuses on the controlled experiment, the main section of the chapter provides an overview of the essential elements in such controlled experiments: the research hypotheses, the different types of variables that need to be defined, the sampling units which can be people or artifacts in informatics, random assignment and, finally, statistical analyses that allow generalization of a conclusion from a sample to a population. Although the examples in this and subsequent ­chapters are taken from the medical field, the study design methods are generic. As such, the content is applicable to the evaluation of information systems in other domains.
