It includes one or more observations that are drawn from the population and the measurable characteristic of a sample is a statistic. Sampling is the process of selecting the sample from the population. For example, some people living in India is the sample of the population.
Hypothetical Population. The population in which whose unit is not available in solid form is known as the hypothetical population. A population consists of sets of observations, objects etc that are all something in common. In some situations, the populations are only hypothetical.
In other words, it is defined as the population of all the individuals or objects that are finite. For statistical analysis, the finite population is more advantageous than the infinite population. Examples of finite populations are employees of a company, potential consumer in a market.
There are two different types of data sets namely, population and sample .
In probability sampling, the population units cannot be selected at the discretion of the researcher. This can be dealt with following certain procedures which will ensure that every unit of the population consists of one fixed probability being included in the sample. Such a method is also called random sampling.
All the students in the class are population whereas the top 10 students in the class are the sample.
The existing population is defined as the population of concrete individuals. In other words, the population whose unit is available in solid form is known as existent population. Examples are books, students etc.
This is called a population bottleneck. Bottleneck Effect.
A population is the number of organisms of the same species that live in a particular geographic area at the same time, with the capability of interbreeding. For interbreeding to occur, individuals must be able to mate with any other member of a population and produce fertile offspring.
Populations can occur on various different scales. A local population can be confined to a spatially small area, i.e., the fish in one pond. However, this locality can operate on a regional, countrywide, island or continental scale; it may even make up the entire species. If individuals of local populations are able to disperse between other local ...
Because most spawning sites are separated by land or deep water, each group of salmon that are born in a certain spawning site makes up the local population within that site; although the conditions within the routes available for dispersal to other sites are not impossible for the salmon to withstand, they are rarely found to move between sites.
If individuals of local populations are able to disperse between other local populations, this is called a metapopulation. Population biology is the study of population characteristics and the factors that affect their size and distribution.
The fluctuations are usually in response to changes in the abiotic and biotic factors, which act as limiting factors against indefinite exponential growth of populations. For example, when food resources are plentiful and environmental conditions are favorable, populations may grow. Conversely, when predation is strong, populations may become depleted.
Life history traits, such as the maturation rate and life span, can affect the rate of growth of a population; if individuals mature later, the population will grow more slowly than if they mature relatively young .

Also known as target audience, this term refers to a group of people that possess certain attributes that can be classified properly to separate them from the entire population.
Healing Helpers Co. is a company that provides physiotherapeutic services to high-performance athletes. When the business was conceived by its founders they decided to pick the state of Washington as their market, since many Olympic athletes live and train there.
The interaction between the species in the population and the environment is called as Population ecology . N.A is the term denoted for the population size i.e the number of organism in a population in the Population ecology and population biology. The fall out in the number of organism is called as Population decline. Drop in the number of the organism within a population for a small amount of time is called as Bottleneck population, which is due to environmental factors. Overpopulation occurs when the number of species in a population increases more than the capacity the ecosystem or the environment could hold is Over-population.
Population can also be defined as the one which consist of a similar group of species in a particular habitat and who have the ability to produce offspring is called as Population . There are various termed related to population such as population size, decline, population ecology, population biology and bottleneck. Animal population study and its biological relation such as evolution, population size, growth, traits and regulation is called as Population biology.
