b) Preliminary assessment of the performance of utilities and comparison with the other utilities in the sector by using quartile method that take into account the similar conditions.

c) Based on the preliminary results, the utilities are able to:

- Determine what areas should and can improve the performance of their utilities;

- Identify utilities under "most effective" quartile group in need of improvement and access to information of the utilities.

- Identify and apply the appropriate measures to improve their own utilities


3.2.3. Quartiles


In descriptive statistics, the quartiles (quartiles) is three points of data sets (in order from small to large) divided into 4 parts with equal number, including

  • First quartile (Q1) (Quartile 1/ lower quartile/ the 25th percentile); 

  • Second quartile (Q2) or median (Quartile 2 / Median/ the 50th percentile);

  • Third quartile (Q3) (Quartile 3/ upper quartile/ the 75th percentile)

For example, the ratio of capacity utilization of the utilities participated in database 2014 as shown in the Annex 3.10 of the Report. It included 70 utilities with ratio of capacity utilization ranged from 24.78% to 260%.



  • Arranged 79 values in order from small to large and divided into 4 parts with an equal number (each consists of 22 values ​​of 22 utilities). The value at the point of division is quartile value Q1 = 66.08; Q2 = 74.03% and Q3 = 90.42%;

  • As results, 25% of the utilities with smaller proportion (or equal to) 66%, 50% of the utilities with smaller proportion (or equal to) 74% and 75% of the utilities with smaller (or equal to) 90%;

  • Each utility can know their ratio of capacity utilization and need to be improved if belong the “risk” group. For improvements, the utility can review the experience of some utilities of the higher quartile group with similar conditions.
