thanks i dont have a problem sending the questions to the company cause my sister works there so she will be on thier tail to fill the forms asap. my only problem is the supervisor not telling her before adminstring the questions...i just hope am not in trouble for that

hi everyone, i am currently writing my dissertation and on chapter 3 methodology,
i have already administered the questionnaires but my problem is that my supervisor wants me to change a few things so  CAN QUESTIONNAIRES BE CHANGED AFTER it has been adminstered?
