Where can I find information about the selection of participants for a phenomenological research? Thanks

What exactly is it that you are researching?

Phenomenology is more a description of a research style than something that is researched.

I am doing a report on phenomenology. Phenomenology as a method used in qualitative research. Like Grounded theory, Ethnography, Case study, etc. The only part I haven't really explored in my paper is how to select participants while conducting a phenomenological study.
Thanks.

Exactly. Phenomenology is a method, not a thing to be researched... so truthfully, I think how to select participants while conducting a phenomenological study is sort of a trick question.

The research would be "A Phenomenological Study of _________".

How you select your participants will be based on what is in the blank, not on the fact that the study is a Phenomenological one.

Despite this, you may find some helpful links here:
