Aims
• To gain insight to the meaning of rigour and
its importance for robustness in all research.
• To gain understanding on how rigour can be
maintained to achieve robustness in the
different stages of the research process of
the different research approaches
(paradigms).
• To appreciate the strategies to achieve rigour
in the different stages of research.

Learning Outcomes
At the end of the session the student will be able
to:
o understand the meaning and the importance of rigour in
research;
o understand how rigour is judged in the different research
paradigms;
o describe ways to achieving rigour in research studies;
o identify some of the common pitfalls in the process of
achieving rigour in research;
o highlight research knowledge and skills as appropriate to
address these pitfalls.

Rigour for Robustness
Analyses involve attending to inconsistencies and
diversity
Present the richness of detail in data,
researcher’s assumptions must be clarified
upfront and context of the study must be
explained
Validation through reference to coherence and
fruitfulness of findings, participants’ orientation and
to new research problems
Seek out negative/deviant cases

Rigour through reporting on findings
and making conclusions
• Personal/Professional Bias – prevent
highlighting some issues while obscuring
others?
• Address ethical aspects of research – which
sometimes can be compromised due to political

Editor's Notes

  • #7 Http://atlasti.com/rigor-social-science-research/ it is necessary to avoid confusing research rigor with concepts such as measurement precision, quantification, and generalizability. These concepts are choices that must be made by each investigator in determining how to best meet his or her research objectives and are not something that should be inherently desired in-and-of-itself.
  • #10 Moreover there are different approaches in research.
  • #11 They being on a continuum rather than concrete entities, would made achieving scientific rigour, an issue far more complex than it seems.
  • #19 findings adequately corroborated with other researchers How comprehensive and relevant are the theoretical conclusions
  • #20 explore, describe, compare, or test hypotheses.
  • #23 explore, describe, compare, or test hypotheses.
  • #24 explore, describe, compare, or test hypotheses.
  • #28 explore, describe, compare, or test hypotheses.
  • #31 Were findings adequately corroborated with other researchers? How comprehensive and relevant are the theoretical conclusions? Does the research contribute to on-going dialogue about the phenomenon?
  • #32 findings adequately corroborated with other researchers How comprehensive and relevant are the theoretical conclusions
