Oh man! If I had figured that out, I would've skewed the poll myself!![]()
A woman (man?) after my own heart. I'm an epidemiologist and get annoyed when I can see that a survey isn't going to answer the question it thinks that it is asking.
In real life I mean, I don't tend to analyze DIS polls! In this case, I assume the multiple choice was an accident (is it the default?) as the choices seem mutually exclusive to me.
ETA - since one could have had multiple previous trips to compare against, I suppose that the options aren't mutually exclusive. Perhaps the 2014 was as good as the 2012 trip, better than the 2010 trip, and worse than the 2007 trip.
