I'm starting my dissertation in which I'm creating a mobile application for public use.
My problem is I need evidences to support my hypothesis and I was informed that I will only be allowed to collect data from users inside the company for which I'm doing the app, since the application won't be released in time of my deadline.
I think this might invalidate my data since these are users who are aware of the application development.
I thought I could do some quizzes and try to have "outside" people to fill them but I'm not sure if this enough to support my hypothesis since these people didn't had any contact with my application.
So my question is if using data from quizzes about a possible solution (like mine) is enough to support my dissertation since I can't let people try my app by themselves.
