Advantages of computer-aided qualitative data analysis Efficient, save time, assist the management of larger samples, good for research teams Can make the research process more systematic and explicit, which makes it seem more valid or trustworthy Can enhance the researcher’s creativity, by allowing more time to experiment and play with data
Cont.…. Organised and controllable data set Support for coding Searching text and codes Support for comparative analysis Models, networks and diagrams Interface with quantitative data
Limitations of computer –aided qualitative data analysis Time constraints Can become overwhelmed by larger samples and the wider volume of data that the software can technically manage. Need to learn how to use the software(and need to buy it)
Cont. Distance or hinder creativity Machine between researcher and data Limited guidance Selecting appropriate programs Changing categories/moving information
