Heterogeneity


core definition

Heterogeneity means literally 'of a different kind'.


explanatory context

Heterogeneity is the opposite of homogenous, which means 'of the same kind'.

 

The heterogeneity of a group on any given variable is best measured by a statistic such as the coefficient of variation, which expresses the dispersion of the data as a proportion of the mean value. The larger the coefficient of variation, the greater the heterogeneity and the smaller it is, the greater the homogeneity.


analytical review

BusinessDictionary.com (2016) :

Fundamental characteristic of services which results in variation from one service to another, or variation in the same service from day-to-day or from customer-to-customer. Heterogeneity makes it hard for a firm to standardize the quality of its services. Opposite of homogeneity.
