Reliability and Validity of Qualitative and Operational Research Paradigm Pak.j.stat.oper.res. Evaluating the quality of research is essential if findings are to be utilised in practice and incorporated into care delivery. However, validity in qualitative research might have different terms than in quantitative research. Fundamental concepts of validity, reliability, and generalizability as applicable to qualitative research are then addressed with an update on the current views and controversies. hޔT�n�0�>n�,�� �{�^0�۰���%�9�U����J�n];`�ER�A�B��4+�iΠH�!s�N����?�@R!���R�jׂ�B�'�������ֳ���n������o|����G���M�o��}�l^�37�%��-f��da��3DO���jb������I��q�?������ For all secondary data, a detailed assessment of reliability and validity involve an appraisal of methods used to collect data [Saunders et al., 2009]. Reliability and Validity in Qualitative Research [Page 273] It is important for qualitative studies to emulate the scientific method in striving for empirical groundedness, generalizability, and minimization of bias (Hammersly, 1992). 0000001559 00000 n Because, although the term ‘reliability’ is usually applied as a concept for testing or evaluating quantitative research, the idea is also used in all kinds of research. ...

Validity and reliability of research and its results are important elements to provide evidence of the quality of research in the organizational field. Reliability refers to the degree to which scale produces consistent results, when repeated measurements are made. VALIDITY AND RELIABILITY IN QUALITATIVE RESEARCH H.I.L.
