case study examining the experiences of youth who is transgender and their family in a rural mid-western community
As I was reading this idiographic study example, I wasn't sure whether the example pertained to a single youth/family or multiple youth and family groups. Perhaps we can revise the wording a bit to clarify here.
Suggested revision: "For example, an idiographic study might be a good approach for a case study examining the experiences of a transgender youth and her family living in a rural Midwestern state. Data for this idiographic study would be collected from a range of sources, including (*provide examples of appropriate sources), to gain a very holistic picture of this family's experiences."
