4.4 Data analysis
Content analysis and descriptive analysis were used in qualitative analysis. Content analysis was carried out according to the theories that are used for testing data. Because the group of key informants was a specific group, each key informant was interviewed three times to obtain all the information needed. The data were tested by reading the field notes taken from the interviews to the informants in order to have an opportunity to check the data directly with the data source and some important direct quotes can be placed in the study results (Maxwell, 1992).
