If an estimate cannot be given, the PI should provide an explanation.
If using existing data, state “Not applicable.”
Anticipated maximum number of participants in the research. A range is not acceptable.

More specific characteristics of the potential research participants that the PI may be interested in, such as a specific age group, race, occupation, hobby, etc.
Any sensitive category should be described more specifically here by specifying the type of illness, mental disorder, etc. that the project focuses on.
Strategy(ies) the PI will use to draw the final sample.
