Cluster sampling is used when "natural" groupings are evident in the population. The total population is divided into groups or clusters. Elements within a cluster should be as heterogeneous as possible. But there should be homogeneity between clusters. Each cluster should be a small scale version of the total population. Each cluster must be mutually exclusive and collectively exhaustive. A random sampling technique is then used on any relevent clusters to choose which clusters to include in the study. In single-stage cluster sampling, all the elements from each of the selected clusters are used. In two-stage cluster sampling, a random sampling technique is applied to the elements from each of the selected clusters.The main difference between cluster sampling and stratified sampling is that in cluster sampling the cluster is treated as the sampling unit so analysis is done on a population of clusters (at least in the first stage). In stratified sampling, the analysis is done on elements within strata. In stratified sampling, a random sample is drawn from each of the strata, whereas in cluster sampling only the selected clusters are studied. The main objective of cluster sampling is to reduce costs by increasing sampling effeciency (This contrasts with stratified sampling where the main objective is to increase precision.).
One version of cluster sampling is area sampling or geographical cluster sampling. Clusters consist of geographical areas. A geographically dispersed population can be expensive to survey. Greater economy than simple random sampling can be achieved by treating several respondents within a local area as a cluster. It is usually necessary to increase the total sample size to achieve equivalent precision in the estimators, but the savings in cost may make that feasible.
In some situations, cluster analysis is only appropriate when the clusters are approximately the same size. This can be achieved by combining clusters. If this is not possible, probability proportionate to size sampling is used. In this method, the probability of selecting an element in any given cluster varies inversely with the size of the cluster.

Computer clusters are used to make a collection of 2 or more computers appear as a single computer to the user community. Clusters are used to provide increased reliability, and/or to increase the performance available from a single computer. There are fundamentally 4 types of clusters:
- Director based Cluster
- 2-node clusters
- Multi-node clusters
- Massively Parrallel clusters
All cluster implementations attempt to eliminate Single Points Of Failure. Director-based-Cluster's and Beowulf clusters are typically implemented primary for performance reasons. 2-node clusters are typically implemented primarily for fault-tolerance.
Massively Parrallel clusters below
A computer cluster is a group of connected computers that work together as a parallel computer. One of the more popular implementations is a cluster with nodes running Linux as the OS and Beowulf software (both free software) to implement the parallelism. Sun Microsystems have also released a clustering product called Grid engine.
Clusters were originally developed by DEC in the 1980s. They not only support parallel computing, but also shared file systems and peripheral devices. They are supposed to give you the ability to use any program without problems or slowing down.
A cluster of computers is sometimes referred to as a server farm.
In the Linux world, there are also variants called Mosix and DistCC. Mosix provides automatic process migration in a homogeneous cluster of Linux machines, while DistCC provides parallel compilation when using GCC.

Matter throughout the visible Universe has, over the course of the Universe's history, aggregated into a range of large-scale structures under the influence of gravity.
The galaxies of HCG (Hickson Compact Group) 87, about four hundred million light-years distant. The large edge-on spiral, the fuzzy elliptical galaxy immediately to its right, and the spiral near the top of the image are members of the group, while the small spiral galaxy exactly in the middle is a more distant background galaxy.

Groups of galaxies (1)
Groups of galaxies are the smallest aggregates of galaxies. They typically have the following properties.
- They contain less than 50 galaxies.
- They have a diameter of about 2 megaparsec (Mpc) (see 1 E22 m for distance comparisons).
- Their mass is approximately 1013 solar masses.
- The spread of velocities for the individual galaxies is about 150 km/s.
Clusters of galaxies
Clusters are larger than groups, although there is no sharp dividing line between a group and a cluster. When observed visually, clusters appear to be collections of galaxies held together by mutual gravitational attraction. However their velocities are too large for them to remain gravitationally bound by their mutual attractions, implying the presence of an additional invisible mass component. X-ray studies have revealed the presence of large amounts of intergalactic gas. This gas is very hot, around 108K, hence emits X-rays. The total mass of the gas is greater than that of the galaxies by roughly a factor of two. However this is still not enough mass to keep the galaxies in the cluster. Since this gas is in approximate equilibrium with the overall cluster gravitational field, its distribution in the cluster traces out the overall cluster gravitational field, and therefore allows calculation of the total mass distribution in the cluster. It turns out the total mass deduced from this measurement is much larger than the mass of the galaxies or the hot gas. The missing component is known as dark matter and its nature is unknown. In a typical cluster perhaps only 5% of the total mass is in the form of galaxies, maybe 10% in the form of hot X-ray emitting gas and the remainder is dark matter.
Clusters typically have the following properties.
Note: clusters of galaxies should not be confused with star clusters such as globular clusters and open clusters, which are structures within galaxies.
- They contain 50 to 1000 galaxies, hot X-ray emitting gas and large amounts of dark matter
- The distribution of these three components is approximately the same in the cluster.
- They have total masses of 1014 to 1015 solar masses.
- They typically have a diameter of 8Mpc (see 1 E23 m for distance comparisons).
- The spread of velocities for the individual galaxies is about 800-1000 km/s.
- The average distance between clusters is approximately 10 Mpc.
Superclusters
Groups, clusters and some isolated galaxies form even larger structures, the superclusters.
At the very largest scales of the visible universe, matter is gathered into filaments and walls surrounding vast voids. This structure resembles a foam. See large-scale structure of the cosmos.

Star clusters are physically bound systems of stars. In order of low compactness to high compactness (and in some sense also age) they range from stellar associations to open clusters to globular clusters.
Star clusters are held together by the gravitation of their members. Due to both external (encounters with massive objects, influence of the host galaxy) and internal (encounters with other cluster members, stellar evolution) influences, clusters slowly evaporate. Their lifetime varies from a few million years for loose associations to many billions (milliards) of years for massive globulars.
The brightest and nearest stellar clusters are visible with the naked eye. The most prominent open clusters are the Pleiades and Hyades in Taurus, but h+Chi Persei can also be a spectacular sight outside the glare of human settlements.
The brightest globular cluster is Omega Centauri, visible with the naked eye from the southern hemisphere. The best known globular cluster in the northern hemisphere is M13 (modestly called The Great Globular Cluster) in Hercules.
In general clusters, due to their rather homogeneous stellar population and relatively well-known distances, play an important role in astrophysics and astrometry.
An open cluster is exactly that: A relatively loose collection of stars. Stars are normally separated by a few light years although they can be closer. Eventually, interactions and the slightly different orbits of the stars around the galactic centre will force the open cluster to disperse. Large open clusters will form streams, vast groups of stars sharing a common motion through space but separated by tens of light years. Our Sun is in the Ursa Major Stream at the moment, but isn't a true member, just passing through. Also at this stage, the most tightly bound members of the former open cluster will still be close together but not close enough to be called an open cluster. This is a moving cluster, most of the stars in Ursa Major are members of the Ursa Major Moving Cluster. This was once the core of the Ursa Major Stream. Mirfak (&alpha Persei) is the lead star in the Alpha Persei Moving Cluster, another easy moving cluster. Distant moving clusters can't readily be detected since the proper motions of the stars need to be known.
Of the well known clusters, the Hyades and the Pleiades, the Hyades are very nearly a moving cluster, being relatively sparse and well separated. In a few million years, they will be a moving cluster. They were both formed at around the same time (give or take a hundred million years) and in the same manner. A cloud of gas, like M42 today, begins forming stars. Since the cloud is of a finite size then the stars will form close by each other. Eventually they drive away the remaining nebula and appear as another open cluster.
Globular clusters aren't found in the plane of the galaxy, but all around it. Many of them are probably the cores of galaxies long since merged into ours, having had all their gas, dust and dark matter stripped from them until only the denser stars remain. Others were formed in much the same way as open clusters, but on a much, much grander scale. There is a low mass globular currently being formed in the SMC, astronomers use this as a unique insight into the formation of these objects since no other nearby sites like this are known. When a globular is forming, it has to form from a molecular cloud and a relatively dense one. These are rare, and explain why a galaxy has far, far less globulars than it does galactic clusters. Also, the rate of condensation of the molecular cloud must be low. It's no good forming massive O or B stars because they'll just explode after a few million years. The majority of stars that have to be formed are those of the classes similar to our sun, F, G and K. These will burn steadily for billions of years and not be so violent as to evaporate the nebula before the cluster has grown to the size needed to be a globular. Lastly, the globular, being very dense compared to other regions of space, will be ejected from the plane of the galaxy and enter a stable halo orbit.
