DELPHI METHOD IN QUANTITATIVE RESEARCH
A graduate-level illustrated introduction to and tutorial the Delphi method, discussing quantitative applications and explaining fuzzy math approaches to Delphi networks.
Why we think it's important: The Delphi method has been used primarily as a qualitative approach in the social sciences. While the previous edition highlighted many of the quantitative uses of Delphi, the 2014 edition provides an illustrated tutorial on its applied mathematics, giving students the basis for undertaking their own quantitative Delphi analyses.
New in the 2014 edition:
