3.1.3. The Entropy Weights

Finally, the entropy weights *W<sup>l</sup>* are calculated as the level of change in each criterion *l*:

$$\mathcal{W}\_l = 1 - \bar{E}\_l(p); \ l = 1, \ 2, \dots \\ L\_\prime \; 0 \le \mathcal{W}\_l \le 1. \tag{6}$$

By focusing on the distribution of responses, the entropy measure simultaneously encompasses measures of central tendency and the data variability.
