What is decennial census?
The Decennial Census is actually two Censuses taken concurrently Census of Population (1790-present) counts numbers of persons and selected social & economic characteristics, the Census of Housing (1940-present) counts numbers of residential units and selected physical & financial characteristics. The Constitution states:
This is part of a population selected to predict information about the population as a whole?
sample
Randomly selected portion of the population?
sample
What is population sampling?
Population sampling is the process in which a group of individuals are selected to represent a population for the purpose of statistical analysis. Population sampling allows the analyzers to learn about a population without studying every individual in it.
The variation in the population as measured by the standard deviation has little or no effect in determining the size of a sample selected from the population True or False?
The answer is False
What is the definition of demographer?
Demographics, or demographic data, are selected population characteristics used in government, marketing or opinion research, or the demographic profiles used in such research.
What is a small part used to represent an entire population?
Sample-a small group selected by researchers to represent the most important characteristics of an entire population. (according to my book)
Why are you using sampling?
Usually we are interested in the characteristics of large populations of items or people. It would often prove costly or impossible to measure these characteristics for the entire population. We therefore measure them for a carefully selected sample of the population and attempt to make scientific inferences about the entire population from the characteristics of the sample.
What characteristics must population first have for nautral selection to occur?
Individuals are selected, but in the population of organisms there are many variations, some better at survival and reproduction than others, and against the immediate environment, what natural selection really is, these beneficial variations will be selected.
What is a subset of measurements from a population?
A subset of measurements from a population is a smaller group of data points selected from the entire group of data points in the population. This subset is chosen to represent the overall characteristics of the larger population and is used for analysis or inference about the population as a whole.
Which type of natural selection in which the mean characteristics of a population are preserved?
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
What is the difference between r selected and k selected species?
R- Selected species have high population densities while k-selected species have lower population densities

A subset of a population selected to represent the population is a?
sample
A ramdonly-selected group that is used to represent a whole population?
A sample is a randomly-selected group chosen to represent a larger population for research or analysis. Sampling aims to provide insight into the characteristics and behaviors of the entire population based on the traits observed in the sample. It is an essential method in statistics and research to draw conclusions about a larger group based on a subset of its members.
What is a smaller subgroup of the population being studied?
A smaller subgroup of the population being studied is called a sample. This sample is selected to represent the larger population and allows researchers to draw conclusions and make inferences about the entire group based on the characteristics of the sample.
