Ulf-Dietrich Reips outlines sixteen standards for Internet-based experimenting, summarizing key considerations and recommendations for conducting effective online experiments. The article discusses ideal circumstances for conducting studies online, precautions in Web design, useful techniques, common errors to avoid, and what should be reported. It covers topics such as randomization, recruitment, generalizability, dropout, experimental control, identity checks, multiple submissions, configuration errors, motivational confounding, and pre-testing. Techniques like "warm-up," "high hurdle," password methods, "multiple site entry," randomization, and incentives are explained. The article emphasizes the importance of careful design and methodological, procedural, technical, and ethical considerations. It also highlights the advantages of Internet-based experiments, such as increased access to participants, reduced cost, and the ability to reach specific populations. However, it also notes limitations, such as the need for specialized hardware for physiological measurements and the potential for self-selection bias. The article concludes with sixteen standards for Internet-based experimenting, including the use of Web-based tools, pretesting, avoiding configuration errors, linking to multiple sites, running experiments offline, using the warm-up technique, analyzing dropout, and ensuring data quality. The article stresses the importance of establishing standards to ensure the reliability and validity of Internet-based research.Ulf-Dietrich Reips outlines sixteen standards for Internet-based experimenting, summarizing key considerations and recommendations for conducting effective online experiments.
