A Web-based experiment or "Internet-based experiment" is an experiment that is conducted over the Internet. Psychology and linguistics are probably the disciplines that have used these experiments most widely, although a range of other disciplines use web-based experiments. Within Psychology most web-based experiments are conducted in the areas of Cognitive and Social Psychology.〔Reips, U.-D. (2007). The methodology of Internet-based experiments. In A. Joinson, K. McKenna, T. Postmes, & U.-D. Reips (Eds.), The Oxford Handbook of Internet Psychology (pp. 373-390). Oxford: Oxford University Press.〕〔Reips, U.-D. & Krantz, J. H. (2010). Conducting true experiments on the Web. In S. Gosling & J. Johnson, Advanced Internet Methods in the Behavioral Sciences (pp. 193-216). Washington, DC: American Psychological Association.〕 This form of experimental setup has become increasingly popular because researchers can cheaply collect large amounts of data from a wide range of locations and people. A web-based experiment is a type of online research method. == Introduction == Experiments are an integral part of research, however, their integration with the Internet has been gradual. There are three main categories of experiments: * Controlled experiments, done in a laboratory setting, attempt to control for all variables then test for a single effect. * Natural experiments, conducted after a large scale event which was prohibitively difficult or impossible to control, collect as many variables as possible then draw correlations. * Field experiments, observed in a natural setting where less controls can be applied, have the advantage of better external validity. While natural and field experiments adapt well online, controlled (also known as laboratory) experiments have had some hurdles. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Web-based experiments」の詳細全文を読む スポンサード リンク
