Mobile data collection
Mobile data collection applications make use of mobile devices, such as smartphones or tablets, to collect quantitative data in the field. Currently, numerous mobile phone applications for both Android and iOS exist. These applications allow you to build a survey form to collect specific data.
Some tips for selecting a mobile data collection application:
- Consider what type of data you need to collect - for example, does the application allow you capture photographs or sound clips?
- How does the application manage the data collected? For example, is the data integrated into to a single database or saved in separate files.
- Does the application allow you to setup advanced logic? This will aid in the cleaning of the data afterward.
- Offline ability
- Licence of the application, for example, proprietary or open source.
- Who does the data belong to? Are you the sole owner of the data or does the license state that the application developer can use the data?
- Security or privacy settings. This is important when capturing sensitive data, for example relating to health.
- The platform. Is the application available for both Android and iOS? Or only one of these? And what phones do you have available in your group?
