What do we mean by survey data? What are good data and how do we recognise them?
Nicholas Bateson tackles these questions and, in doing so , offers a redefinition of the validity of survey data and suggests a new approach-or a more assertive formulation of an old approach-to the testing of data for validity.
He specifies conditions that must be satisified if survey data are to be called valid, and brings out the implications of his ideas for the management of survey error.
