Random sampling is the gold standard of sampling strategies because of its unbiasedness and the possibility to evaluate the reliability (precision) of the resulting estimates [ 1– 4].
"However, pinpointing new antibiotics using the standard technique of sampling soil for bacteria is tricky.
United States Department of Agriculture (USDA) standard of soil sampling for nutrient management was maintained during sampling (USDA 2007).
The error bars represent the standard deviation of samples.
The standard deviation of sample 'c' in size distribution of particles is more than the other three samples.
Significance of this decrease was evaluated by one standard deviation of sampled changes in the rate of occurrence.
This allows us to conclude that the average and standard deviation of sampled droplets can be used for statistical estimation of entire sample volume.
First we tested the MALDI-triple quadrupole MS approach on plasma samples, which is currently the standard type of sample for drug monitoring.
Open image in new window Fig. 2 Scatter diagram of projection value of standard sample of water resource resilience.
According to the standards of the OIE, samples with CFT titres ≤ 1/5 were considered negative.
