When ‘self-selected’ isn’t bogus
Two opportunities for public comment that will expire soon, and where StatsChat readers might have something to say
- Stats New Zealand wants to hear from people who use Census data. They have a questionnaire on how you use the data, and how this might be affected if they change the Census in various ways. It’s open until Friday May 3
- Public submissions on the new ‘legal highs’ bill close on Wednesday May 1. The bill is here. You can make a submission here. The Drug Foundation have a description and recommendations here.
This sort of public comment is qualitative, rather than quantitative. Neither the Select Committee nor Stats New Zealand is likely to count up the number of submissions taking a particular view and use this as a population estimate, because that would be silly. What they should be aiming for is a qualitatively exhaustive sample, one that includes all the arguments for or against the bill, or all the different ways people use Census data.
