Explanation:

Sampling can be defined as a process used by researchers to collect, obtain or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

Confidentiality refers to the act of sharing an information that is expected to be kept secret, especially between the parties involved. Thus, a confidential information is a secret information that mustn't be shared with the general public.

This ultimately implies that, confidentiality requires that access to collected data be limited to research staff rather than being accessible to other team members or persons who aren't authorized to have access but might be interested in getting the information.
