For example, Hanushek and Kimko (2000) used country scores from international achievement tests to construct measures of the average quality of the labor force of each country, which were then used to explain cross-country differences in growth rates.
When the average quality of teachers in fourth grade falls from one year to the next, for example, the performance of the fourth-graders also drops as expected.A bias-free measure of teacher quality allows the economists to wring fascinating conclusions from their data-set.
In the Netherlands, for example, the average number of adoptions annually is 28.
Some quantities characterizing the quality of such systems (quality measures) are defined and evaluated; they are, for example, the average number of level crossings, the average number of maxima, and the departure from normality.
For example, the average age of people earning their Ph.D.'s in life sciences is 32.
For example, the average score for watersheds with complete WQI scores was 82.4 (good but not excellent water quality).
In France, for example, the average teacher salary is $33,000, and in Greece teachers earn an average of $25,000.
For quality control, we calculated the average quality score of sites and reads of each sample.
For example, the data quality of the imaginary nation in the example above is 0.419.
For example, the Quality-of-Life items correlated between r =.49 and r =.95 with the average of inter-item correlations being r =.73.
