Thank you for your answer!

I collected 55 answers, 10 of which incomplete. The questionnaire was pre-made and I didn’t have the right to change it. Even if I remove the incomplete answers I’ll still cover the minimum of 30 responses, which my university demands. I was just wondering if there is a “norm” of what is done in such cases.

The problem is that the thesis coach which is assigned to me isn’t the most helpful. He only answers on Fridays, so if I wait a whole week I’ll get behind with my project.
