Developed by the American Institutes for Research (AIR), AIR Lighthouse empowers the users to ask their own questions of complex datasets without specialized research or statistical skills. Users can create custom-run tables, graphs and other statistics over the Internet. This product is designed to integrate multiple complex surveys, assessments, or other data collections. It actually captures the knowledge of expert statistical analysts and stores this knowledge along with the data itself. To the user, the system seems to "know the data" and to choose the right analytic procedures. This knowledge enables the system to hide the technical details and sophisticated statistical procedures from the user, who sees only perfectly tailored answers to his or her queries.
