Question

which dispersion is used by a scocial worker​

Answer 1

Answer:

In social research, we often wish to know the extent of homogeneity and heterogeneity among respondents with respect to a given characteristic. Any set of social data has values which may characterize heterogeneity. The set of social data is typically characterized by the heterogeneity of values.

In fact, the extent to which they are heterogeneous or vary among themselves, is of basic importance in statistics. Measures of central tendency describe one important characteristic of a set of data typically but they do not tell us anything about this other basic characteristic.
