	Statistical population - Biocrawler (Site not responding. Last check: 2007-10-26)
		In statistics, a statistical population is a set of entities concerning which statistical inferences are to be drawn, often based on a random sample taken from the population.
		Notice that if we choose a population like all crows, we will be limited to observing crows that exist now or will exist in the future.
		For each bird in the population of crows there is a weight, and the set of these weights is called the "population of weights".

	Population - Wikipedia, the free encyclopedia
		In biology, plant and animal populations are studied, in particular, in a branch of ecology known as population biology, and in population genetics.
		Populate, as a verb, means the process of populating a geographic area, as by procreation or immigration.
		Population transfer is a term referring to a policy by which a state forces the movement of a large group of people out of a region, most frequently on the basis of their ethnicity or religion.

		Population is also used to refer to a set of potential measurements or values, including not only cases actually observed but those that are potentially observable.

		Statistics is a science which involves collecting, organizing, summarizing, analyzing, and interpreting data in order to facilitate the decision-making process.
		Inferential or inductive statistics are methods of using a sample data taken from a statistical population to make actual decisions, predictions, and generalizations related to a problem of interest.
		Statistical sampling is particularly useful in the analysis of a large bill of materials.

	SAS Elementary Statistics Procedures : Statistical Background
		A statistic is to a sample as a parameter is to a population.
		Approximately 68 percent of the values in a normal population are within one standard deviation of the population mean; approximately 95 percent of the values are within two standard deviations of the mean; and about 99.7 percent are within three standard deviations.
		Consider a new population consisting of the means of all the samples that could possibly be drawn from the original population.

		In the most common sense of the word, a population is the collection of people—or organisms of a particular species—living in a given geographic area.
		In biology, a population denotes a breeding group whose members breed mostly or solely among themselves, usually as a result of physical isolation, although biologically they could breed with any members of the species.
		Population density is a measure of the number of people or organisms per unit of area.

		The essence of this model is that the statistical description of a small set of observations, the sample, can be generalized to the population of which the sample is a subset.
		Their answers are then generalized to the whole population of voters and used to predict the outcome of the next election.
		The statistical generalizations of this kind of experiment are only used to be able to make decissions, e.g., whether a certain medication cures a disease.

		Table 1 presents estimates of population and sex ratio, birth and death rates, growth and fertility rates for the world, Arab countries and ESCWA member countries for the years 2005 and 2010.
		The table shows that the population of ESCWA region was estimated to be 192 million in 2005 and is expected to grow to 214 million in 2010 with annual growth rate of 2.5 per cent.
		In 2005, the population in the ESCWA region is fairly young, with 37 per cent under 15 years of age.

		When a comparison of DNA profiles derived from evidence and reference samples fails to exclude an individual(s) as a contributor(s) of the evidence sample, statistical assessment and/or probabilistic reasoning are used to evaluate the significance of the association.
		The DAB believes it is for the courts to decide whether or not Bayesian statistics are solely the responsibility of the trier of fact.
		Statistical analyses are sometimes thought to yield automatic rules for making a decision either to accept or reject a hypothesis.

		The N-VALUE: The total number of members in the population under study is called the N-value of the population or the population size.
		Chance error: Because a sample is not the whole population, a statistic is not expected to be the exact value of the parameter.

	Dr. Arsham's Statistics Site
		Statistics is a science of making decisions with respect to the characteristics of a group of persons or objects on the basis of numerical information obtained from a randomly selected sample of the group.
		There are many statistical procedures for determining, on the basis of a sample, whether the true population characteristic belongs to the set of values in the hypothesis or the alternative.
		Almost all standard statistical analyses are conditioned on the assumption that the population is homogeneous, meaning that its density (for continuous random variables) or probability mass function (for discrete random variables) is unimodal.

	Power Analysis
		In most situations in statistical analysis, we do not have access to an entire statistical population of interest, either because the population is too large, is not willing to be measured, or the measurement process is too expensive or time-consuming to allow more than a small segment of the population to be observed.
		The third experiment found an effect that was statistically significant, and perhaps substantially higher than the first experiment, although this is partly masked by the lower level of precision, reflected in a confidence interval that, though narrower than Experiment 2, is substantially wider than Experiment 1.
		In the case of the data mentioned above, the F statistic that is significant at the.05 level yields a 90% confidence interval for the RMSSE that ranges from.0190 to.3139.

	U.S. GAO - Summary
		Decennial census data need to be as accurate as possible because the population counts are used for, among other purposes, allocating federal grants to states and local governments.
		Recalculating these allocations using statistical population estimates from the Accuracy and Coverage Evaluation and the Post Enumeration Survey--independent sample surveys designed to estimate the number of people that were over- and undercounted in the 2000 and 1990 Censuses--would have produced the following results.
		Fourth, statistical population estimates from the 2000 Census would have shifted a smaller percentage of funding compared to those using the 1990 Census because the difference between the actual and estimated population counts was smaller in 2000 compared to 1990.

		When these clues give inconsistent indications of the statistical population, it is time to consider carefully whether the study's conclusions are valid.
