- What sampling strategy is used and is it appropriate and justified?
Plano-Clark and Creswell suggest that Theory or Concept Sampling is used to “generate a theory or explore a concept.” (Plano-Clark and Creswell, 2015, P 234). I believe that Chan and So used this method for sampling in their research. They chose a specific group that would help them to generate their theory, which is that servant leadership qualities can develop in adolescents, as well as to develop specific concepts within that theory. I believe that this sampling strategy is appropriate for the research. Plano-Clark and Creswell do state that in “a well-written qualitative report, the researchers should describe and defend the specific type of purposeful sampling strategy that they used in their study.” (Plano-Clark and Creswell, 2015, P 335). Chan and So (2015) do not justify or provide a clear explanation of the reasoning for the sampling method they have chosen.
- Is the sample size appropriate?
Plano-Clark and Creswell (2015) suggest that the sampling size should be as few as one and as many as 30 when studying a classroom as a case study. Chan and So had 11 participants in their study. I believe that this is an appropriate sample size for the classroom as a case. (Plano-Clark and Creswell, 2015, P 336).
- Is the data collected appropriate?
The data was collected in this study through focus-group interviews. The data was then recorded into audio recordings. I feel that the validity and significance of the data collected would be more valuable if Chan and So collected data in different ways as well. They conducted interviews by a main researcher and then the results were coded and categorized. It would be beneficial to include a formal observation analysis or other documented data that would strengthen the results of the research.
- Are the data gathered ethically and thoughtfully?
The data for this research was collected ethically. Chan and So (2017), state “prior to each focus-group interview, interviewees gave their written consent, acknowledging their understanding of this research, agreeing to participate in the interview and giving permission for the audio recording.” (Chan and So, 2017, P 21). Chan and So secured appropriate permissions in their research and treated participants respectfully.

Hi Sadie,
Given that the study design is not described then it is hard to determine if the sample size was appropriate or not. However, my understanding is that because the goal was to present a servant leadership training framework then this appears to be more of a grounded theory study. This type of design would make more sense given the sampling strategy you identified above.
Well done.
