I did a survey where the participants give vote for each question (Agree, disagree, etc). The years of experience varies among the participants, some of them are experts and some are novice. Say that 90% of the responders said that they are Agree on all of the questions in the survey.
How can I statically find the relation between the survey's result and the participants' years of experience in order to verify that 90% agree on the survey's questions?
