Correct sampling, the Glossary

Index Correct sampling

During sampling of granular materials (whether airborne, suspended in liquid, aerosol, or aggregated), correct sampling is defined in Gy's sampling theory as a sampling scenario in which all particles in a population have the same probability of ending up in the sample.[1]

Aerosol

An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. Correct sampling and aerosol are aerosols.

See Correct sampling and Aerosol

Bias (statistics)

Statistical bias, in the mathematical field of statistics, is a systematic tendency in which the methods used to gather data and generate statistics present an inaccurate, skewed or biased depiction of reality.

See Correct sampling and Bias (statistics)

Granular material

A granular material is a conglomeration of discrete solid, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when grains collide).

See Correct sampling and Granular material

Gy's sampling theory

Gy's sampling theory is a theory about the sampling of materials, developed by Pierre Gy from the 1950s to beginning 2000sGy, P (2004), Chemometrics and Intelligent Laboratory Systems, 74, 61-70. Correct sampling and Gy's sampling theory are sampling (statistics).

Particle filter

Particle filters, or sequential Monte Carlo methods, are a set of Monte Carlo algorithms used to find approximate solutions for filtering problems for nonlinear state-space systems, such as signal processing and Bayesian statistical inference.

See Correct sampling and Particle filter

Particle in a box

In quantum mechanics, the particle in a box model (also known as the infinite potential well or the infinite square well) describes the movement of a free particle in a small space surrounded by impenetrable barriers.

Particulate matter sampler

A particulate matter sampler is an instrument for measuring the properties (such as mass concentration or chemical composition) of particulates in the ambient air. Correct sampling and particulate matter sampler are aerosols and Meteorological instrumentation and equipment.

See Correct sampling and Particulate matter sampler

Particulates

Particulates or atmospheric particulate matter (see below for other names) are microscopic particles of solid or liquid matter suspended in the air. Correct sampling and particulates are aerosols.

See Correct sampling and Particulates

Sampling (statistics)

In statistics, quality assurance, and survey methodology, sampling is the selection of a subset or a statistical sample (termed sample for short) of individuals from within a statistical population to estimate characteristics of the whole population.

See Correct sampling and Sampling (statistics)

Suspended solids

Suspended solids refers to small solid particles which remain in suspension in water as a colloid or due to motion of the water.
