Population mean
| Glossary of Statistical Terms |
- The mean of the numbers in a numerical population. for example, the population mean of a box of numbered tickets is the mean of the list comprised of all the numbers on all the tickets. the population mean is a parameter. c.f. sample mean.

Mean, английский
- The mathematical average of a range of numbers (calculated by dividing the sum total of all the items in the range by the total number of items in the range).
- Среднее (значение).
- The arithmetic average of a set of values. a measure of central tendency of the distribution of a set of replicate results. often abbreviated by an x with a bar over it.
- Среднее значение, среднее. мера усреднения наблюдений выборки, формируемая путем суммирования всех величин и деления полученной суммы на количество наблюдений.
- As a general term implies the medium, but a mean of bad observations can never make a good one.
- [1] an average (e.g., mean high water is the average depth of water at high tide). [2] equidistant from two extremes.
- Среднее значение. если не оговорено иное, означает среднее арифметическое.
- The expected value of a random variable. arithmetic average of a sample.
- A way to calculate the average of a series of numbers
- A way to calculate the average of a series of numbers an average determined by adding up a group of numbers, and then dividing that total by the number of numbers. for example, to calculate the mean of “10, 20, 30, 40, 50”: first, add the numbers (10+20+30+40+50 = 150), then count the numbers (5), then divide the total by the number of numbers (150/5 = 30)

Population, английский
- A definable set of individual units to which the findings from statistical examination of a sample subset are intended to be applied. the population will generally much outnumber the sample. in re-randomisation statistics the process of applying inference
- See stock.
- A collection of units being studied. units can be people, places, objects, epochs, drugs, procedures, or many other things. much of statistics is concerned with estimating numerical properties (parameters) of an entire population from a random sample of units from the population.
- A group or number of people living within a specified area or sharing similar characteristics (such as occupation or age).
- Население; народонаселение; генеральная совокупность (в выборочном наблюдении); популяция (биол)
- Население
- 1. the number of people living in a country or town population statistics show that the birth rate is slowing down. the government has decided to screen the whole population of the area. 2. the number of patients in hospital the hospital population in the area has fallen below 10,000.
- Популяция
- Население; популяция -
- Популяция. в клинических исследованиях совокупность субъектов, обладающих какими-либо одинаковыми признаками (пол, возраст, диагноз).
- Население; популяция
- Any group of individuals, usually of a single species, occupying a given area at the same time; groups of organisms with homologue (same) alleles. p. cycle: changes in the numbers of individuals in a population which repeatedly oscillate between periods of high and low density. p. density: allowing a mathematically precise reflection - pd. • absolute: pd = number of individuals/unit area or volume [1/m2] or [1/m3] • relative: pd allows only a simple comparison (pd <, =, >, ? etc.). p. dynamics: the variations in time and space in the sizes and densities of populations; distribution due to changing food resources - the stability of a population depends upon abiotic factors, intraspecific competition (density dependent), natality, mortality etc. p. ecology: the study of the variations in time and space in the sizes and densities of populations, and of the factors causing those variations. p. fluctuation: variations over time in the size of a population. p. growth: is zero, when the birth rate equals the death rate (see carrying capacity). nt+1 = nt + r nt, current number of individuals r = (natality + immigration) - (mortality+emigration) r, intrinsic rate of growth (see density) p. pyramid: a means of illustrating the age structure of a population diagrammatically, by placing the youngest age class at the base and stacking successive age classes above it. p. regulation : a tendency in a population for some factor to cause density to increase when it is low and to decrease nt, momentary number of individuals when it is high. n0, number of individuals at start
- Generally, a collection of individuals with common characteristics. in statistics, a potentially infinite collection of independent (->independence) units that include all units of a specified type with attention paid only to the agggregate (->aggregation) property of the collection. a sample of data drawn from this population is a subset of the units constituting this population and scientific generalizations from such samples are limited by the size of the population originally specified (->model, ->representation).
- The process of scanning content to compile and maintain an index.
- Fish of the same species inhabiting a specified geographic area.

Mean squared error (mse), английский
The mean squared error of an estimator of a parameter is the expected value of the square of the difference between the estimator and the parameter. in symbols, if x is an estimator of the parameter t, then
Maximum likelihood estimate (mle), английский
The maximum likelihood estimate of a parameter from data is the possible value of the parameter for which the chance of observing the data largest. that is, suppose that the parameter is p, and that we observe data x. then the maximum likelihood estimate of p is
