Guttman Scaling
Herv´e Abdi
1 Introduction
Guttman scaling was developed by Louis Guttman (1944, 1950) and
was first used as part of the classic work on the American Soldier.
Guttman scaling is applied to a set of binary questions answered
by a set of subjects. The goal of the analysis is to derive a single
dimension that can be used to position both the questions and the
subjects. The position of the questions and subjects on the dimension
can then be used to give them a numerical value. Guttman scaling
is used in social psychology and in education.
2 An example of a perfect Guttman scale
Suppose that we test a set of Children and that we assess their
mastery of the following types of mathematical concepts: 1) counting
from 1 to 50, 2) solving addition problems, 3) solving subtraction
problems, 4) solving multiplication problems, and 5) solving division
problems.
