Validity also establishes the soundness of the methodology, sampling process, dâ¦ reliability, validity and triangulation, if they are relevant research concepts, particularly from a qualitative point of view, have to be redefined in order to reflect the multiple ways of establishing truth. Validity Reliability; Meaning: Validity implies the extent to which the research instrument measures, what it is intended to measure. Are the research questions clear and are the features of the study design similar to them? Accordingly, qualitative research has a more difficult task when trying to establish the reliability and validity of its data. Validity and reliability of research and its results are important elements to provide evidence of the quality of research in the organizational field.

What is Validity and Reliability in Qualitative research? Because, although the term âreliabilityâ is usually applied as a concept for testing or evaluating quantitative research, the idea is also used in all kinds of research. 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). However, validity is better evidenced in quantitative studies than in qualitative research studies. {��4�\H�-��EOc7�0��G�4��, �ğ ��> endobj 53 0 obj <> endobj 54 0 obj <>/ProcSet[/PDF/Text]/ExtGState<>>> endobj 55 0 obj <> endobj 56 0 obj <> endobj 57 0 obj <> endobj 58 0 obj <> endobj 59 0 obj <> endobj 60 0 obj <>stream �(&dX-� )BA�� 0��n�XZ��-�,��\DV��!5�P��8�D �$f7\V�62��$�yFn��m�$��S�(��ۛ_⨚i��Z��#��=�#YSt�Yozi;�a0@/��Q��Y��h��]�tym�.w_�D�ѯ�&K�9�ո�F�_��?��t�@��n��,��K/�U�w��ֺ��I��wזԾ��`��I�]��[;��Ȯgi�[˚'} ��-Uuv��:ѵn�L�G:�N�ݤ��f��e:��iZlb�4��D�iz��Z>��vgő��Z�8��ļ�붓w^��;��|(��(��o�~F� �=T0�&�,��g�?�[��S��^�*��K�fr�x�� G�W�m�g:�9Ш(2e(U��u��&��R�&�֪^ ;N��N��|�_\�#?�A��ƸAmL��ȵť�q0 �K��=��lqq�ɰg� �rE��`��V�fB!j��v�Wㆄ�\��}_�lUej1��?ʁُU�.
