PIEL Data
Read full descriptionHide full description
PIEL Data is an app designed to help researchers manage the data collected from projects using the PIEL Survey app (available on the Apple Store). The app only handles the specific file format of the PIEL Survey app and cannot process other data file types. The PIEL Survey app enables researchers to conduct “in the moment” surveys. The data is received in the form of individual “csv” files which then have to be merged manually using spreadsheet software. The PIEL Data app enables researchers to import the participant data files into to the app database. This data can then be exported into a merged “csv” file which can easily be imported into third party spreadsheet or statistical software. The PIEL Survey app has been used by more than 40 universities in the US and Europe with more than 50 per reviewed publications. The PIEL Data app will streamline the process of conducting such projects.
