A method for evaluation of metric properties of response scales
- 1973
-
Reports (other academic/artistic)abstract
- To permit certain statistical operations verbal response categories in questionnaire response scales must be given appropriate numbers. In this study the routines used to assign such numbers are discussed. A method to evaluate the metric properties of response scales, simultaneously being an alternative way of assigning proper numbers, is proposed. For this method, based on subjective estimation, two criteria related to commonality of meaning are suggested. Finally the method is demonstrated in an empirical study on eight different response scales.

Measures of attitudinal polarization
- 1974
-
Reports (other academic/artistic)abstract
- Criteria for measures of attitudinal polarization, i.e. degree of opposition among people on a specific issue, are proposed and some formulas, including the standard deviation, are evaluated in relation to the criteria.The formulas were also tested on empirical data with respect to level, dispersion and agreement of received values. The measures on the whole showed a high degree of agreement. There clearly exist instances when the standard deviation is not an adequate measure of attitudinal polarization. Some guidelines are given for the choice of constant values in some proposed formulas.

Om "objektivering" av det subjektiva eller utvärdering av Bärbyledsalternativ
- 1973
-
Reports (other academic/artistic)abstract
- Utvärderingen av trafikledsalternativ i ett tjänstemanna-PM inom Uppsala kommun baseras på komplexa subjektiva bedömningar på olika nivåer i beräkningsprocessen, som leder fram till s.k. nyttoindextal för trafikledsalternativen. En kritisk granskning av framställningen i detta PM görs. Slutsatsen är att framräknade indexvärden inte bör användas som politiskt beslutsunderlag beroende på de metodologiska bristerna. En politisk vägning av alternativ- och konsekvensbeskrivningar för de olika alternativen torde vara att föredra.
