==What is the DataShop?==
 
The DataShop is a data analysis service for the learning science community.  It is both a central repository for research data and a suite of tools to analyze that data.
 
  
The PSLC DataShop provides two main services:
 
* secure storage  of log data that is generated during in vivo experiments
 
* relevant statistical analyses and reports that are based on those data
 
 
Data collection and retrieval is a three-stage process: 
 
# raw data logs are collected either in real-time or after the study;
 
# data are extracted, anonymized, and stored in an analysis database
 
# reports and queries are rendered via the web upon request
 
 
After authenticating on the [http://learnlab.web.cmu.edu/datashop DataShop website], researchers can rapidly access standard reports such as learning curves, as well as browse data using the interactive web application.  To support other analyses, the DataShop can export data to a variety of formats that can then be used in statistical software and other analysis packages.
