Larger sample sizes are typically better because they reduce the likelihood ofsampling errorsand provide a more accurate representation of the population. However, larger sample sizes often increase the impact of practical considerations, like time, budget and the availability of your audience. Ultimately...

A sample is a smaller, manageable version of a larger group. Samples are used in statistical testing when population sizes are too large.

Final milling of samples to produce sample ready for laboratory analysis is a routine task and even small laboratories can produce more than a hundred samples each day. Larger bore core laboratories can be expected to produce many more milled samples each day. Milling involves placing sample that...
With gravimetric sample preparation, laboratories are no longer constrained by the availability of appropriate volumetric glassware, only the required amount of solution that needs to be prepared; the need to round up the volume to the nearest flask size is unnecessary. The amount of substance a...
This chapter focuses on sample preparation procedures for pesticide analysis of food commodities, biological and environmental matrices. This will include pesticides with a broad range of polarity including those that are more amenable to gas chromatography- mass spectrometry (organochlorines, organophosphorus...
Parallelized NGS analysis of tissues from many different patients is also commonplace in clinical genomics pipelines. In these settings, sample or data mislabeling, where datasets are incorrectly associated with a donor, can lead to erroneous conclusions, misdirect future research, and affect treatment...
The tiles on the right side of the dashboard provide a team scorecard. The CFO needs to keep track of their managers and these tiles give them a high-level overview of profit, by using GM%. If the GM% trend is unexpected for any manager, then they can investigate further....
