The Chicago study has city-wide representativeness of a type of early childhood program and the population of children it serves, but at the cost of random assignment.
The benefits of using Google Scholar virtual corpus are the following: 1) wide representativeness of written academic language, 2) possibility of capturing subtle variation in academic patterns, and 3) possibility of comparing linguistic patterns across different academic fields.
Modern ECCE research began with the birth of the U.S. Head Start program in the 1960s; however, policy makers and the public paid little attention to it until several studies that had random assignment or wide representativeness received wide but targeted dissemination to them.
The genome-wide representativeness of these 199 SNP markers for the whole genome in population genetic studies was confirmed using heterozygosity-heterozygosity correlation [ 48]: mean internal relatedness = 0.78, lower bound of 95% confidence intervals from 1000 bootstrap replicates (cil) = 0.444; mean homozygosity by loci = 0.86, cil = 0.596; standardised heterozygosity = 0.87, cil= 0.632.
On the other hand, scientific plots do not have the same wide distribution and representativeness as commercial forest inventory data and often suffer from the 'majestic forest' effect.
Scale issues have wide-ranging effects from the representativeness of data used to validate models to aggregation errors introduced in the model structure.
Nevertheless, the quantitative methods are useful to approach wide-encompassing phenomena with probabilistic representativeness.
According to the Central Limit Theorem, the accuracy of this similarity-based search for candidate SNP markers should increase as the number, diversity, representativeness, and completeness of genome-wide maps increase [ 67].
Hence, it is essential to have studies that include a territory-wide sampling in order to achieve greater representativeness and which take into account methods of design and statistical analysis (e.g. cluster-based analyses) to obtain valid estimates and to explore the influence of patient, health-care professional and PHCT characteristics on the CPV of preventive services in Spain.
