The large number of participants also provides enough power for moderator analyses, which is a capability often available only to meta-analyses. The resulting potential sample size is massive and grants the power to do a class of analyses that could not be considered in a typical study with 100–200 (or even 500–600) users per cell. First, whereas more traditional intervention evaluation studies are usually constrained by budgetary concerns (each participant costs money in order to encourage retention), openly available products generally aim to acquire as many users as possible. Despite the extra care needed to analyze big data, there are some substantial benefits to using a big data approach. Specialized analytic methods are necessary to handle the amount and frequency of data given for a particular user and to accommodate a very large number of users. #See the bigger picture software#Such iterative processes take advantage of the short implementation cycles of software as opposed to more traditional medical interventions. Moreover, since the data are produced during normal usage, they can be immediately useful as a means for assessing not only whether the intervention is effective, but also which aspects and parts of it are more effective than others and how the intervention can be modified to become more effective. Big intervention data, therefore, offer the opportunity to test interventions in the real world, where interventions are actually being found by individuals and used naturalistically. While these datasets are often not designed upfront to answer research questions, and therefore often do not have control groups, they are large in size, are rich in content, and offer a view into the intervention that allows users to interact with an intervention naturalistically. These datasets often fall under the umbrella of “big data,” where big data is defined as a dataset so large and complex that traditional data analytic approaches cannot easily handle them. The big picture is the complete perspective of an issue or a situation.As Internet interventions become increasingly popular-in research settings, but even more so in industry-they yield large datasets that can be used for research purposes.
