Answer to Question 2

By its nature, single subject research is concerned with telling a story of one or more participants, the significant others involved, and the researchers themselves. This telling often involves discussing the overall validity of the study and its outcomes from various perspectives.
Qualitative methods can help explain trends and changes in the dependent variable that are not as evident or objectively identified via visual or statistical analyses.
Qualitative methods can help to explain confounding variables and events that impact the study's outcomes.
Qualitative methods can help in identifying biases or concerns of the researcher as well as other participants.
Qualitative methods can help identify nuances in the setting, participants, independent and dependent variables, etc. that assist others with understanding the external validity of a study.
