The phrase "a sampling ratio" is correct and usable in written English.
It can be used in contexts related to statistics, research, or data analysis where you are discussing the proportion of a sample taken from a larger population.
Example: "In our study, we determined a sampling ratio of 1:10 to ensure a representative selection of participants."
Alternatives: "sample proportion" or "sampling fraction".
The marginal cost to test 10 samples out of 10,000 (for a sampling ratio of 0.1%) is about $2, and can be completed in under an hour.
In the present work, the study population was based on a sub-cohort of 1254 subjects randomly selected from the source sample totalling 8,414 individuals (i.e. a sampling ratio of 15%) stratified by centre, 5-year age class and gender.
When sampling elders, we first calculated a sampling ratio (target number of elders/total number of elders in all of the villages) and then multiplied this ratio by the number of elders in each village [ 20].
The Western medicine files to be sampled were extracted from the complete outpatient claims (excluding dental and TCM services), using a sampling ratio of 0.2%.
When input signal frequency is 780 MHz, a sampling ratio of 20 results in a sampling frequency of 40 MHz.
However, when input signal frequency is 780 MHz, a sampling ratio of 10 results in a sampling frequency of 80 MHz.
When these differ, there is a "sample ratio mismatch," which often voids the results.
A sample ratio was determined for each sample by dividing the average optical density (OD) of the test sample by the average OD of the cutoff control (tested in quadruplicate).
To calculate the amount of eicosanoids in a sample, ratios of peak areas between endogenous eicosanoids and matching deuterated internal eicosanoids were calculated.
As an example, subsampling mixer with integrated filtering, for an RF input frequency of 2.42 GHz with a sampling frequency of 100 MHz, achieves a high sampling ratio of 20 [33].
Because the government has established guidelines stating that no more than 10% of all data can be drawn for research, we applied for a random sample of these patients with a 3.4 1 sampling ratio.
