A Move from Statistical Significance?
In a recent post by correspondent Steve King: Are Statistically Significant Research Methods Passe?. " ... A growing number of surveys are being based on informal groups of respondents rather than statistically significant population samples ... ". Speaking about the use of questionnaires. I comment at his post as well, where I agree it is a growing trend. It is also like the trend of design versus quantitative analyses. Like the 'Blink' hypothesis. A form of generate-and-test, but do not forget the test. Classic statistically sound methods are still important. It is OK to use roughly exploratory methods to understand the landscape, but not to make the big decisions. See related previous post, which suggests that chat is more important than carefully directed instruments.
