What is considered a subpopulation?
What is considered a subpopulation?
The term “subpopulation” describes a specific group of individuals with common patient characteristics (e.g., race/ethnicity, age, risk factors) that is the target of an intervention or a policy recommendation.
What is a subpopulation in ecology?
Subpopulation-an arbitrary spatially-delimited subset of individuals from within a population (as defined above).
What is an ethnic subpopulation?
A sub-population of individuals who are labeled and cateogorized by the general population and, often, by the members of the group itself, as being of a particular type of ethnicity. An Ethnic subpopulation subject to discrimination by a more powerful subpopulation.
What is a subpopulation analysis?
We can use subpopulation analysis to check the fairness of a model across various subgroups of interest. In the same way we would do for a partial dependence plot, we need to choose one variable to compute the analysis. Both categorical and numeric variables can be used to define subpopulations.
What is another word for subpopulation?

How do subpopulations form?
Over many generations competition can cause subpopulations to diverge morphologically, ecologically, and genetically as each group becomes specialized in ways that reduce competition. Genetic differences can proceed to speciation, meaning that the two subpopulations become two reproductively isolated species.
What are subpopulation changes?
Microevolution reflects changes in DNA sequences and allele frequencies within a species over time. These changes may be due to mutations, which can introduce new alleles into a population. Eventually, genetic drift can cause a subpopulation to become genetically distinct from its original population.
What does ethnic stratification mean?
Ethnic stratification is a system. of stratification wherein some relatively. fixed group membership (e.g., race, religion, or nationality) is utilized as a. major criterion for assigning social.
Which is the greatest barrier to assimilation?
Some of the greatest barriers to assimilation were prejudice, discrimination, stereotyping, and federal law itself.
- Many ethnic groups ran into prejudice in America.
- Discrimination was also a large problem, mostly because of prejudice.
- Stereotyping, a major problem for immigrants, also affected assimilation.
What are representative samples?
A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group. For example, a classroom of 30 students with 15 males and 15 females could generate a representative sample that might include six students: three males and three females.
What is an example of Peripatric speciation?
An example of this is the London Underground mosquito, a variant of the mosquito Culex pipiens, which entered in the London Undgerground in 19th century. Evidence for its speciation includes genetic divergence, behavioural differences, and difficulty in mating.
What is the difference between subpopulation and metapopulation?
The entire set of populations in a region is called a metapopulation, or “population of populations.” The component populations are often called subpopulations (see Concept 42.5 in the textbook). Subpopulations may (or may not) be linked to one another by dispersal—the movement of individuals among populations.
What does subpopulation mean?
Subpopulation. A subconcept of a population that shares one or more additional properties is called a subpopulation. For example, if the population is all Egyptian people , a subpopulation is all Egyptian males; if the population is all pharmacies in the world, a subpopulation is all pharmacies in Egypt.
What are some examples of population density?
Population density is the measure of the population number per unit area, according to About.com. An example would be people per square mile, which is calculated by dividing the total number of people by the land area in square miles. Population density is often used to estimate the number of people in any given area of a country.
What is an example of population distribution?
Population Distribution: The population is the whole set of values, or individuals, you are interested in. For example, if you want to know the average height of the residents of India, that is your population, ie, the population of India. Population characteristic are mean (μ), Standard deviation (σ) , proportion (P) , median, percentiles etc.
How is a sample related to a population?
Population and Sample are two important terms in the subject ‘Statistics’. In simple terms, population is the largest collection of items that we are interested to study, and the sample is a subset of a population. In other words, sample should represent the population with fewer but sufficient number of items.
