|
|
|
Indirect Observation
|
A research technique that makes use of pre-recorded behavior from secondary sources, such as telephone records or sales records.

Sex Ratio
|
Gender ratio is the ratio of males to females in a population. The human sex ratio is of particular interest to anthropologists and demographers. ...

Logistic Growth
|
n
|
|
|
Exponential Growth
|
growth whose rate becomes ever more rapid in proportion to the growing total number or size.
|
|
|
Density Independent
|
In population ecology, density-independent processes are the result of such physical factors as weather or environmental pollution.
|
|
|
Individual
|
single; separate.
|
|
|
Biotic Potential
|
is the maximum reproductive capacity of a population under optimum environmental conditions. Full expression of the biotic potential of an organism is restricted by environmental resistance, any condition that inhibits the increase in number of the population.
|
|
|
Clumped Distribution
|
s the most common type of dispersion found in nature. In clumped distribution, the distance between neighboring individuals is minimized. This type of distribution is found in environments that are characterized by patchy resources.
|
|
|
Random Distribution
|
In probability and statistics, a probability distribution assigns a probability to each measurable subset of the possible outcomes of a random experiment, survey, or procedure of statistical inference. ...
|
|
|
Regular Distribution
|
The normal distribution is the most common type of distribution, and is often found in stock market analysis. Given enough observations within a sample size, it is reasonable to make the assumption that returns follow a normally distributed pattern, but this assumption can be disproved.
|
|
|
Uniform Pattern Distribution
|
A uniform distribution, sometimes also known as a rectangular distribution, is a distribution that has constant probability. the latter of which simplifies to the expected for .
|
|
|
Population Density Formula
|
Population density is the measure of the number per unit area. It is commonly represented as people per square mile (or square kilometer), which is derived simply by dividing...
|
|
|
Age Structure
|
A population pyramid, also called an age pyramid or age picture diagram, is a graphical illustration that shows the distribution of various age groups in a population, which forms the shape of a pyramid when the population is growing.
|
|
|
Monogamous
|
When cultural or social anthropologists and other social scientists use the term monogamy, the meaning is social or marital monogamy. Marital monogamy may be further distinguished between: marriage once in a lifetime; marriage with only one person at a time, in contrast to bigamy or polygamy;

|
|
Polygamous
|
practicing, relating to, or involving polygamy.
|
|
|
Plumage
|
a bird's feathers collectively.
|
|
|
Birth Rate
|
the number of live births per thousand of population per year
|
|
|
Death Rate
|
the ratio of deaths to the population of a particular area during a particular period of time, usually calculated as the number of deaths per one thousand people per year.
|
|
|
Density Dependent
|
The amount of increase that a specific variable has gained within a specific period and context. For investors, this typically represents the compounded annualized rate of growth of a company's revenues, earnings, dividends and even macro concepts - such as the economy as a whole.
|
|
|
Density Dependent
|
A limiting factor of a population wherein large, dense populations are more strongly affected than small, less crowded ones.
