Successful research using qualitative data relies on the rigour and thoroughness of the data analysis methods; and, consequently, this manual focuses on how qualitative data can be rigorously analysed. Key to the qualitative analysis process is diminishing any doubt surrounding the reliability and validity of qualitatively produced findings, and formulating a serious method of data analysis (Miles and Huberman, 1994). This Toolkit describes in detail how the data analysis of a higher degree study was conducted, using NVivo qualitative data analysis software. By applying the detailed guidelines set out in the Toolkit to your own research, you will be able to clearly demonstrate rigour in your data analysis to a level required in a higher degree study.
