PIEL Data App

The PIEL Data App merges survey data files received from participants in a PIEL Survey research project.

Key features are as follows.

• The PIEL Data app will merge participant data from multiple PIEL data files.
• The data can be exported into a csv file suitable for importing into spreadsheet or statistical software.
• Duplicate data is automatically removed.
• The data is checked for consistency with the PIEL Survey control file.
• Files from multiple surveys can be imported.

The app only merges original PIEL Survey data files. If you import the data files into spreadsheet software and export them into a csv file, the format of the file may change and the PIEL Data app will detect that change and show an error.

The PIEL Data app does not collect any data other than the data imported by the user and no data is transmitted unless the user chooses to share the merged data file. Please see the privacy and confidentiality features.

By downloading the PIEL Data app, users agree to be bound by the PIEL Survey Terms of Service.

FAQs

How can I delete the survey run data?

Simply swipe left the project in the "Projects" tab. This will delet ethe project and all imported data. The exported merged data files will not be deleted.

How can I send and delete the survey run data?

Long press on the data file in the "Files" tab. This will show a context menu for sharing or deleting the file.

I can't import the survey data file.

You must first import the PIEL Survey file that was used to run the surveys. This file is used by the app to validate the imported data files.

What happens if I import duplicate data?

The PIEL Data app checks all imported survey runs for duplicates. A survey run is considered a duplicate if the install id and the start time for a survey run are identical. If this occurs, the existing record is overwritten.

What is the "Install ID"?

The install id is a unique identifier created when the app is installed. This provides a double check on uniqueness of the participant. If the Researcher accidentally issues a duplicate participant ID to a second participant, the "install ID" will make this obvious. The "install ID" can be seen on the data tab, just under the participant ID.

Can I edit the data?

The PIEL Data app does not allow editing of data. It is purely a tool to merge multiple data files. Any editing should be done on the exported file by spreadsheet or statistical software.
