I'm of the opinion that they don't really fight you on how the course should be counted. If you in good faith believe this is a statistics based course and the name of the course agrees I really doubt you will have an issue assigning it to some variation of "statistics/math". I took. ie. Food Toxicology (might raise a few eyebrows but was actually great preparation for microbiology) - so I'm sitting there trying to decide if I mark it down as biology or some sort of "other science". And that's why I sometimes find the whole GPA thing that schools do so comical. If classification isn't strictly enforced anyone can beef there science GPA up. Whatever - don't fret it. Read the rules and assign the classes honestly and I doubt you'll have an issue.
