In the interview editor (and in the API interview stats call) I get the following numbers:
The groups seem to consist of complementary categories, so they all should amount to the same total question count. They don’t:
Group . . . . . . . . . Total
Valid/Invalid . . . . . . 109
Not/Answered . . . . 101
Super/Interviewer . . 99
How do these differences come about? What is the actual total question count in this interview?
I need to use these figures in a program which verifies the interviews and then either rejects or approves them.
