The material may be solid, liquid, gas, a material of some intermediate characteristics such as gel or sputum, tissue, organism, or a combination of these.Even if a material sample is not countable as individual items, the quantity of the sample may still be describable in terms of its volume, mass, size, or other such dimensions.
A textile sample is a piece of cloth or fabric designed to represent a larger whole. A small sample, usually taken from existing fabric, is called a swatch , whilst a larger sample, made as a trial to test print production methods, is called a strike off .
using experience – small samples, though sometimes unavoidable, can result in wide confidence intervals and risk of errors in statistical hypothesis testing. using a target variance for an estimate to be derived from the sample eventually obtained, i.e., if a high precision is required (narrow confidence interval) this translates to a low ...
Aliquot of a sample, in chemistry and other sciences, a precise portion of a sample or total amount of a liquid (e.g. precisely 25 mL of water taken from 250 mL); Aliquot in pharmaceutics, a method of measuring ingredients below the sensitivity of a scale by proportional dilution with inactive known ingredients
Sample or samples may refer to: Sample (graphics), an intersection of a color channel and a pixel; Sample (material), a specimen or small quantity of something; Sample (signal), a digital discrete sample of a continuous analog signal; Sample (statistics), a subset of a population – complete data set
Fisher's exact test (also Fisher-Irwin test) is a statistical significance test used in the analysis of contingency tables. [1] [2] [3] Although in practice it is employed when sample sizes are small, it is valid for all sample sizes.
Example of samples from two populations with the same mean but different dispersion. The blue population is much more dispersed than the red population. In statistics , dispersion (also called variability , scatter , or spread ) is the extent to which a distribution is stretched or squeezed. [ 1 ]
In 2000, the jazz flautist James Newton filed a claim against the Beastie Boys' 1992 single "Pass the Mic", which samples his composition "Choir". The judge found that the sample, comprising six seconds and three notes, was de minimis (small enough to be trivial) and did not require clearance. Newton lost appeals in 2003 and 2004.
