168In many fields of social studies it would be useful to measure the degree
of global satisfaction (or agreement) of a population based on individual opinions
about several aspects. Some examples regard, for instance, the measurement
of customer satisfaction, of students’ or graduates’ opinions about university
teaching, of subjective well-being and so on. This problem concerns the more
general framework of measuring complex phenomena that are not directly observable
and hence approximated by a set of elementary (one-dimensional) indicators.
The problem of synthesizing a set of variables thus arises. A common
solution is to construct a composite indicator, which synthesizes all the elementary
indicators by means of a weighted average. There is a widely developed
statistical literature on this subject. Here we propose an alternative approach.
We consider a set of elementary variables that are observed in a population.
Each variable represents the individual degree of satisfaction about one of several
aspects related to the complex phenomenon. In aiming to synthesize them,
starting from their joint distribution, we define a new variable that measures
global individual satisfaction. To evaluate the degree of global satisfaction for the
entire population, we propose a normalized index, which takes values between 0
(maximum dissatisfaction) and 1 (maximum satisfaction). Specifically, this index
measures the distance between the observed distribution of the new variable and
the theoretical one, which refers to the situation of maximum dissatisfaction (all
individuals are not at all satisfied for every aspect).
