Abstract: The statistical procedures used for data processing have to be considerate depending on measurement variables level: nominal, ordinal, interval or ratio type. Here are presented some examples for ordinal variables, where calculated mean is misleading and gives a wrong interpretation. For the categorical variables, we propose an indicator resulted from the informational entropy, as a measure of the responses distribution in a survey. Calculations are made for a Likert scale, survey data from 1991 to 2010. The indicator allows us to make a global characterization of the distributions, items ranking, dynamic comparisons and patterns identification.

Keywords: Scales of measurement; Informational Entropy and Energy; Likert Scalea.
