Preliminary Guidelines for Empirical Research in Software Engineering by B.A. Kitchenham, S.L. Pfleeger, L.M. Pickard, P.W. Jones, D.C. Hoaglin, K. El-Emam, and J. Rosenberg (January 2001) provides a set of guidelines aimed at improving the quality of empirical studies in software engineering. The guidelines are based on a review of research guidelines for medical researchers and the authors' own experience in conducting and reviewing software engineering research. The guidelines are intended to assist researchers, reviewers, and meta-analysts in designing, conducting, and evaluating empirical studies. They are also intended to help software engineering journal editorial boards develop guidelines for reviewers and policies for handling the design, data collection, analysis, and reporting of empirical studies. The guidelines are divided into six main areas: experimental context, experimental design, conduct of the experiment and data collection, analysis, presentation of results, and interpretation of results. The authors emphasize the importance of defining the research context, including background information, research hypotheses, and related research. They also stress the importance of clearly stating the research questions and hypotheses, and of defining the population and sampling methods. The guidelines also address the need for appropriate blinding, the use of controls, and the definition of treatments and outcome measures. The authors also highlight the importance of ensuring that the experimental results are analyzed correctly, in accordance with the study design. They emphasize the need to avoid statistical errors, such as those that may arise from small sample sizes or inappropriate use of statistical techniques. The guidelines also address the need to monitor and record any deviations from the experimental plan, including drop-outs and non-response in surveys. The authors also emphasize the importance of ensuring that the data collection process is well-defined and that the data is collected in a consistent and accurate manner. Overall, the guidelines aim to improve the quality of empirical studies in software engineering by providing a framework for researchers to follow in designing, conducting, and evaluating their studies. The authors believe that the adoption of these guidelines will not only improve the quality of individual studies but also increase the likelihood that meta-analysis can be used to combine the results of related studies. The guidelines are a first attempt to formulate a set of guidelines for empirical research in software engineering, and the authors believe that further discussion and debate are needed before definitive guidelines can be developed.Preliminary Guidelines for Empirical Research in Software Engineering by B.A. Kitchenham, S.L.
