Data Management Cases
Your team is collecting data on people in the sample, including race, ethnic background and health (as an alternative: you are collecting data from a vulnerable sample that can be harmed by human activity or public interest).
Your team is collecting data via the Unemployment office on people who obtain training via their planned training schemes. You collect data on their background, reasons for becoming unemployed and health, so the Unemployment office could provide for their needs to plan future training. During your data collection one of the participants wishes to retrieve their data (does not wish to continue in the research), but you have already anonymised all the collected data.
