Data collection is the process of gathering and measuring information on targeted variables in an established system, which then enables one to answer relevant questions and evaluate outcomes. Data collection is a research component in all study fields, including physical and social sciences, humanities, and business.

Who is responsible for data collection?

The Principal Investigator (PI) is responsible for the overall conduct (including administration and compliance) and results of the research, including the collection of data.

Where do we collect data from?

Surveys, interviews and focus groups are primary instruments for collecting information. Today, with help from Web and analytics tools, organizations are also able to collect data from mobile devices, website traffic, server activity and other relevant sources, depending on the project.
