One or more observations drawn from a larger collection of observations or universe (population).
A small portion of a material or product intended to be representative of the whole. Statistically, a sample is the collection of measurements taken from a specified population.

A part of anything presented for inspection, or shown as evidence of the quality of the whole; a specimen; as, goods are often purchased by samples.
the measurement of a signal level at one specific instant in time.
Digital representation of audio.
A digital "snippet" of a sound, which can be triggered by a MIDI keyboard. Can be a drum sound, orchestral sound or vocal phrase.
In analog to digital signal processing, a sample is taken at regular intervals to establish the electrical potential (voltage) present in an analog system at a given point in time. Each sample is then assigned a digital value. In telephony, sample values are established by a codex, and range from zero to 255. (Though, for most â€œvoice gradeâ€ connections the actual range of codex values is between zero and 127.) Each sample value is transmitted across the digital phone network and used to re-create a facsimile of the original analog signal at the other end of a phone connection.
A part of a larger group of people. The sample may or may not be chosen by chance. This term can also be a verb, meaning to choose this smaller group.
A specimen that is taken from food and tested for the purpose of identifying a foodborne pathogen or various kinds of chemical contaminants in food.
a single item or specimen from a larger whole or group, such as any single sample of any medium (air, water, soil, etc.).
a group of individual test pieces or specimens
Material collected from a source other than an animal or man for laboratory analysis (such as water sample or soil sample).
Term relates to the act of an individual interacting with a biometric system for the purpose of enrollment, identification or verification. The biometric data collected by the system is referred to as a sample.
A sample that contains data collected over a specified period of time during the execution of the application.
Small quantities of lunar soil or rocks that are sufficiently small to return them to Earth. On each mission several different kinds of samples are collected. Contingency sample consists of 1 to 2 pounds of rocks and soil collected very early in the surface operations so that at least some material will have been returned to Earth in the event that the surface activities are halted abruptly and the mission aborted. Documented sample is one that is collected with a full set of photographs to allow positive identification of the sample when returned to Earth with the sample in situ together with a complete verbal description by the astronaut. Comprehensive sample is a documented sample collected over an area of a few yards square.
In acceptance sampling, one or more units of product (or a quantity of material) drawn from a lot for purposes of inspection to reach a decision regarding acceptance of the lot.
Pieces of a lot provided to registered buyers for an evaluation prior to bidding.
A sample consists of one or more service outputs drawn from a lot, the outputs being chosen at random.
a collection of numbers (measurements or counts) on the quality characteristic (QC) of process variable (PV) of units drawn from a process
Indivisible element of an image that is stored in computer memory. In Microsoft DirectX Transform, a DXSurface is composed of an array of samples. The terms pixel and sample are often used interchangeably.
From Portable Network Graphics (PNG) Specification (Second Edition) ( 2003-11-10) intersection of a channel and a pixel in an image. number of bits used to represent a sample value. In an indexed-colour PNG image, samples are stored in the palette and thus the sample depth is always 8 by definition of the palette. In other types of PNG image it is the same as the bit depth. mapping of a range of sample values onto the full range of a sample depth allowed in a PNG image.
A single number in the image data; for example, the red value of a pixel. A pixel is composed of one or more samples. When discussing physical data layout (in particular, in Image layout), we use "sample" to mean a number stored in the image array. It would be more precise but much less readable to say "sample or palette index" in that context. Elsewhere in the specification, "sample" means a color value or alpha value. In the indexed-color case, these are palette entries not palette indexes.
a datum for one band of an image
A printed piece of the finished product.
a single piece of a paper product that you may request so you can see and feel our quality
a piece of clothing from a line that is specificly created for a shoot or a fashion show. Many samples are one of a kind pieces that are produced before the line is created. Samples are sometimes maked with permanent ink or have defects so that they cannot be resold.
A piece of laminate supplied to customers to give an indication of the colour, design, surface finish and other qualities of the actual product. We provide A5 size samples (210mm x 150mm), one sample per item up to a maximum of five separate items, while larger sizes can be prepared for special requirements.
To make or show something similar to; to match.
a recording of something that was already done, it's nothing synthetic
a small part of something that is intended to show the quality of it
A small quantity of tobacco (around two kilos) typically pulled from the process after the re-drying operation and compressed into a block measuring approximately 13 inches wide by 17 inches long by 4 inches thick. The purpose of a sample is to provide a representation of the overall quality and color of the tobacco being processed and to ensure consistency and uniformity within the blend.
To read the value of a signal at evenly spaced points in time; to convert representational data to sampled data (that is, synthesizing and rendering).
A small (generally 2x2-foot) representation of a decorative concrete installation, used as a selling tool or to experiment with various decorative treatments and techniques for applying materials.
The data obtained from one interruption of an executing program. The sample includes statistical information and a stack trace.
in statistics, a group of data chosen from all the possible data.

a measurement of a very specific point in time and/or a location in space
Measurements from one site or treatment in experiment
One measurement by a data acquisition board, usually consisting of a number which corresponds to a specific reading. Most boards are compared by the number of samples they can measure each second. This Sample Rate is best explained below at Speed.
