| Abstract: | The paper deals with some new indices for ordinal data that arise from sample surveys. Their aim is to measure the degree
of concentration to the “positive” or “negative” answers in a given question. The properties of these indices are examined.
Moreover, methods for constructing confidence limits for the indices are discussed and their performance is evaluated through
an extensive simulation study. Finally, the values of the indices defined and their confidence intervals are calculated for
an example with real data.
