Perhaps we can expand a bit on these examples by highlighting them in a separate Student Example box. This may be a useful way to briefly explain what is meant by the earlier statement "...and remember, you want your sample of artifacts to reflect the diversity of perspectives that you have outlined for your study." Also, I think that a Student Example could bring this important hypothetical scenario to life and keep readers engaged.

It may be helpful to include here a Student Example box with a hypothetical scenario involving a student project using artifacts to answer a qualitative research question. Particularly when I read the last sentence of the paragraph - "...you want your sample of artifacts to reflect the diversity of perspectives that you've outlined for your study" - I wasn't quite sure exactly what this would mean for a student research project.

Perhaps this "for instance" can be formatted as a Student Example. By framing this hypothetical scenario in the context of a student research project, readers may be further empowered to imagine how they themselves might collect observational data for their own projects. The same example details would be included - just in a different format.
