Project manager: Bengt Kriström

The objective of the project is to develop and empirically test relevant theory supporting the use of self-selected
intervals, in a joint effort between economics, psychophysics and statistics. The hypotheses are that the intervals reduce a number of well-known biases, provide a useful picture of
response uncertainty and increase response rates. Lab experiments (GEL and classroom) and field surveys (national and international) will be the methods of the project. Expected outcomes are a better understanding of the merits of using intervals in survey research. Development of underlying theory. Tools for practical use (user-friendly software). A strengthening of co-operation between economics, psychophysics and statistics.
