It depends on the expertise of the researcher. If the researcher has knowledge in qualitative and quantitative then he or she may review research papers on both area.
Halima - Yes, qualitative researcher can review a quantitative research in case he is well versed with mixed methods research. It is a methodology for conducting research that involves collecting, analyzing and integrating quantitative (e.g., experiments, surveys) and qualitative (e.g., focus groups, interviews) research. A researcher trained in mixed methods research has expertise in both qualitative and quantitative research.
Thank you, Dr Manzoor Hussain and i am agreed with you too. But my question was that only qualitative researcher could do it not about mixed method researcher?
In case the qualitative researcher is not aware of the statistical techniques of the paper then how can he review it.If his domain is qualitative research ,say ethnography then how can he say that the paper should have used a regression analysis or not.
I would tend to agree with both Dr Manzoor Hussain and Jaspreet Kaur : minimal knowledge of quantitative analysis is needed in order to adequately judge the use of quantitative methods and the conclusions one might draw from the analyses ; therefore, the researcher should have training either in mixed methods or in quantitative analysis. Personally, I believe all social scientists should have training in both qualitative and quantitative analysis, as these methods are more often than not complimentary and as the use of one over the other should not be dependent on preference or ideology but on the best tool suited to answer the questions/verify the hypotheses at hand. Best of luck !
As a social scientist, I tend to use both methods and both should be part of the curriculum at university. Personally, nothing beats an in-depth interview that stays with you forever. I can recall snippets of interviews done years ago, which can be used and integrated into my current projects. However, my friend, a statistician, speaks as passionately about quantitative methods.
A useful comparison could be to consider reviewing a paper on a topic outside of your own expertise. If you have an awareness of the topic, whether methodological or content-wise, then you can provide insight into the manner in which the study was conducted.
