QUALITY INDICATORS <strong>2017</strong><br />
Example 1: Let us say that, in a particular survey, monthly indices, month with regard to the average of the<br />
previous year, are such as presented in the table below.<br />

Let us further assume that the index of the annual growth rate calculated in the referential annual survey<br />
(average of 2008 compared to the average of 2007) I<br />
0<br />
99, 7 . Since this index is equal to the index calculated<br />
as the (arithmetic) mean in the table of given indices, the calculation is as follows:<br />

Example 2: Let us assume that in two comparable quarterly surveys financial aggregates (in EUR) are being<br />
monitored. The table shows results in both the study survey and the referential survey and the relevant value of<br />
indicator S2.<br />
