I am a first-time post-graduate student in an apparel design field, and I don’t understand statistics very well. I am doing a study on the adoption of 3D apparel design software by major apparel retailer design departments in my country.
I have identified only six retail groups that fit the criteria. I aim to collect data from various companies that fall within each group, but I suspect the each group would have design practices that extends throughout all their brands, as they are all situated in the same office buildings and ultimately overseen by the same merchandising directors.
So far, I have only obtained permission from two of the groups, and have warm leads from another two. The last two have both denied permission.
Would this study still be valid, and if so, how can I back this up statistically?
