Photovoice is a ground-breaking approach to participatory action research. Photovoice is a process by which people can identify, represent, and enhance their community through a specific photographic technique. It can be used as a qualitative research method, as an assessment tool, as a way of gathering data, and as an evaluation tool. But how can I use this method for quantitative analysis with some statistical analysis?
Usually the Ns involved in qualitative research such as photo voice are too small to permit meaningful statistical analysis, so I would not pursue that option unless you have 50 or more participants.
You can quantify your data if it is meaningful. For example you can number the people that apear in each photo, the activities and so on. You can create indexes by, for example, summing up all the activities that apear in each photo. Then you can also perform some basic statistical analysis.
Sibsankar - Since you are using Photovoice as a research technique there is need to increase your sample in purposive sampling research. As a CBPR methodology, you can explore community health and social issues of community participants by using photography, and stories about their photographs, to identify and represent issues of importance to them. There is possibility to present the data of stories generated from photographs in the form of descriptive statistics provided some quantification of data is generated.
As a participatory method, the idea for photovoice is ti hear the lived experience of individuals and showcase through imagery their insights. In this way, quantitative analysis would be ill fitting for the fundamental nature of photovoice. However perhaps you are looking to use traditional photovoice methods and dissemination and then take it a step further to integrate into a mixed method study using quantitative date?
