The objective of this study is to observe the significance of sampling fractions
in spectrochemical analysis of aluminium master alloys.
The third assumption, that sampling occurs with replacement, was examined by calculating the sampling fraction
(i.e., the ratio of sample size to estimated population size).
Where N: total neuron number of CA and subiculum, [SIGMA][Q.sup.-]: total disector neuron number, ssf: section sampling fraction
, asf: area sampling fraction
Despite oversampling isolates from retail chicken meat, we observed that 82% (a greater fraction than the 60% sampling fraction
) of E.
1998) to calculate the sampling variance because Aerial Survey calculates a population estimate using a sampling fraction
based on the number of censused SUs divided by the total number of SUs in the study area.
The area sampling fraction
can then be calculated from this information.
Based on a mathematical model presented in the 2001 Auditing study, and assuming population percentages and rates of overrepresentation similar to those observed in that study, the sampling fraction
(sample size divided by population size) would need to exceed 30% for the natural debiasing process to have a meaningful effect.
