In preparing for a forthcoming supervisory meeting, I’ve been asked to share what I felt were the standout insights from my empirical observations, but for each one explain how I know, how I convinced myself of that, and how I can convince others.

For them it is about trustworthiness and the arguments which can be mounted to make the case, however, assessing the quality of research findings is far from straightforward and is contested in a number of ways. Traditionally, research quality has been judged on the criteria of validity, reliability, generalisability, and objectivity. Validity, simply put, is the extent to which an account adequately represents the phenomenon it purports to. Reliability is related to the replicability of the data generation and analysis; if different people conducted the same study, or the same person on different occasions, would the outcomes be the same? Generalisability refers to the extent what has been learned can be extended to wider populations and objectivity, to how the biases and interests of researcher and researched have been reduced or accounted for.Read More »
