Geoff Hoon picked up this "extrapolation" idea from a Fellow of the RSS -
his boss Jack Straw.
Why should this bit of appraisal be limited to limited to 'cluster
analysis'. Surely the extrapolation idea applies to all ONS social surveys
that all use samples with most using stratified samples just like the Iraq
study. So are statistics from any survey now dismissable among members of
the government on the grounds that they are extrapolations.
Will the ONS and RSS be communicating with Jack Straw and Geoff Hoon on what
appears to be attack on a fundamental idea supporting the production of
National Statistics?
