tailieunhanh - Standards for Internet-Based Experimenting

This article summarizes expertise gleaned from the first years of Internet-based experimental research and presents recommendations on: (1) ideal circumstances for conducting a study on the Internet; (2) what precautions have to be undertaken in Web experimental design; (3) which techniques have proven useful in Web experimenting; (4) which frequent errors and misconceptions need to be avoided; and (5) what should be reported. Procedures and solutions for typical challenges in Web experimenting are discussed. Topics covered include randomization, recruitment of samples, generalizability, dropout, experimental control, identity checks, multiple submissions, configuration errors, control of motivational confounding, and pre-testing. Several techniques are explained, including “warm-up,” “high hurdle,” password methods,. | REPRINT cite as Reips . 2002 . Standards for Internet-based experimenting.

Several techniques are explained including warm-up high hurdle password methods multiple site entry randomization and the use of incentives. The article concludes by proposing sixteen standards for Internet-based experimenting. Key words Internet-based experimenting Web experiment standards experiment method psychological experiment online research Internet research Internet science methodology Introduction We are in the midst of an Internet revolution in experimental research. Beginning in the mid-nineties of the last century using the world-wide network for experimental research became the method of choice for a small number of pioneers. Their early work was conducted soon after the invention of forms on Web pages established user-server interaction Musch Reips 2000 . This medium holds the promise to achieve further methodological and procedural advantages for the experimental method and a previously unseen ease of data collection for scientists and students. Several terms are used synonymously for .
