I then turn to the executive summary, where it says here that "Four groups of people were interviewed: festival/event organisers; medical personnel who worked at … events; volunteers working for [Know Your Stuff New Zealand]; festival attendees/wider New Zealand public… Overall 66 people were interviewed … 911 surveys were completed, with the final survey sample after cleaning totalling 861. The sample was a purposeful, focused, non-random sample." Now, for an organisation such as the Victoria University of Wellington, which prides itself on its academic inquiry, its independence, and its ability to try to really understand the issues, this seems to be one of the most biased documents I've seen, which has used what is called "purposeful, focused, non-random samples", which I think pretty much means asking people who you think will agree with you and getting a result which they wanted.
