You won't get enough data if you ask them to fill out a survey. If you try a single interview you'll see why. You'll end up with pages of notes and venture into problems you had no idea about. If you had asked them to fill out a survey instead, you would've ended up with just a fraction of the information. And world wide or not doesn't matter. I did all my interviews over Skype. |
