@lithpool, thanks so much for the analysis. I love descriptive stats too, but yes, I agree do need to take them with a grain of salt 
I also want to say that my kiddo is personally using an audition coach (MCA) this year and couldn’t be more pleased. We didn’t get a coach to get into more schools, but rather to help with the process, build more confidence and better performance skills, and network with like-minded people. MCA has helped on all aspects of this.
For anyone interested, this discussion is a great one for qualitative reasons people used coaches: http://talk.collegeconfidential.com/musical-theater-major/2069570-coaches-corner-p1.html.
I put the yes/no coach question in there because I wanted to see whether that was a factor in the amount of schools applied/accepted, etc. and from this data set, I don’t think there is much of a difference. But, I didn’t want people to come to the conclusion that coaches aren’t helpful, because people who have used them felt they were a huge asset.
