Abstract:
This paper considers how New Zealand journalists report political polls. Two recent newspaper articles are featured. Perhaps not surprisingly we have detected a tendency for journalists to focus on sample size, to misunderstand the concept of margins of error, and to have little idea as to whether a result is generalisable. We also consider the importance of non-respondents. We wonder if journalists question the validity of survey results they have been given. We ask the question: could a "non-random" convenience survey have as much validity as a more formal survey conducted by a specialist research company?
