“Shocking world of our student drunks” – Where did that come from?
“Shocking world of our student drunks” shouted the 10 June front page headline from the New Zealand Herald.
“Nearly a third of university drinkers have passed out while boozing in the past six months”, it continued. Moreover, “27 percent of men and 9 percent of women say throwing up will not stop their boozing.”
And where did all that come from?
The figures came from a survey of students at just three student dormitories at a single university, and could therefore be symptomatic of a very localised culture, but were presented as picture of student behaviour across an entire country.
The authors of the source paper in the New Zealand Medical Journal carefully reported that their research population was “three student residential facilities in 2006”. In addition to their place of residence these students were very unrepresentative of the student body as a whole in terms of age and sex.
Most percentages quoted were related only to drinkers but sound in the news report as if they were percentages of all students.
Also 40% of those contacted did not take part. Ignoring nonresponse biases the male figures have an unacknowledged margin of error of the order of 7%.
So what is our point?
An implied applicability of the results that goes far beyond what is justified from the research undertaken and oversensationalising to make an attention grabbing story.
