Miscellaneous Notes and Quotes


This Figure illustrates the non-symmetric distribution of the success and failure of a normal sample on an item targeted one logit below the sample. "S", the mean of those succeeding, is closer to the sample mean, "A", than is "F", the mean of those failing.
Ivan Horabin


"Where social measurement has relied heavily on methods borrowed from psychophysics, psychometrics, and economic index numbers, rather than methods well suited to the population sciences, it has encountered seemingly intractable difficulties, which are only exacerbated by adherence to an inadequate doctrine of scale types. A sociology of measurement, allied with an expanded historical metrology, is needed not less for the improvement of measurement technique than for an understanding of the role of quantification in society."
Otis Dudley Duncan, Notes on Social Measurement. 1984 p. xiii


"Unanimity of opinion may be fitting for a church, for the frightened or greedy victims of some (ancient or modern) myth, or for the weak and willing followers of some tyrant. Variety of opinion is necessary for objective knowledge. And method that encourages variety is also the only method that is compatible with a humanitarian outlook."
Paul Feyerabend in Against Method. 1975.

Rejoice! The Rasch model demands variety!
