When should relative measures of dispersion be used?
They may be used-with considerable caution-when the measurements in the various populations being compared were made in different units. Dividing the dispersion estimates by the location estimates eliminates eliminates the differences attributable to differences in measuring units. However, caution is advised because the measurement methods may have differed in the various populations, giving rise to differences in the dispersion estimates having nothing to do with dispersion in the populations. In other words, there could well be differing levels of measurement error across populations.
Why do the blocks that are the same size and shape float at different levels?
Because they are of different materials. If the materials are same then there's no way they'd floats at different levels. It is because of the densities of different matters the level of floating is different for them.
What is a plywood layer?
it is different levels of a very thin wood
Is levels of family stress a dependent variable?
A dependent variable is non manipulative and is affected by the manipulations of the independent variable. In the case given, the different levels of family stress like high and low can be siad as different levels of a dependent varible i.e. stress. So, family stress can be a dependent variable but not the levels of stress
What is a good price per square on wood framing?
Different levels of building will have different "good price" #s.
What are the four levels of organization in the ecosystem?
The four levels of organization in an ecosystem are individuals (organisms), populations (group of individuals of the same species), communities (interacting populations in a specific area), and ecosystems (communities interacting with their physical environment).
How do counties vary across the country?
Counties in the United States vary in size, population, wealth, geography, and governance structures. Some counties are rural with small populations, while others are urban centers with large populations. Additionally, counties may have different levels of economic prosperity and resources, which can influence the services they are able to provide to residents.
List the levels of organization in an ecosystem?
The levels of organization in an ecosystem are: individual organisms (such as plants and animals), populations (groups of the same species), communities (all populations living in a specific area), ecosystems (communities and their physical environment), and finally the biosphere (all ecosystems on Earth).
Does a rise in population mean carbon dioxide levels rise?
Yes, because every person has a carbon footprint, some larger than others. So, as populations increase, so do carbon dioxide levels in the atmosphere.
What is the significance of vectors to the evolution of populations?
"Vector" has several meanings, such as a mathematical idea, or an "infection carrier". Since you mention population evolution, which is treated mathematically, I will assume you mean the former. A vector is an ordered set of numbers, such as the relative population levels of various different genotypes or phenotypes. One can think of the vector as a direction in a high dimensional abstract space. As populations evolve, these relative levels change (in response to natural selection), so the direction of the corresponding vector changes, roughly towards a direction that maximizes the total population number (if the environment itself is not changing). This increases overall "fitness".
What is a list of the levels of organization in the biosphere?
the levels of biological organisation from broadest to smallest are: the biosphere, biomes, ecotones,ecosystems, communities, populations, organisms, organs and organ systems, tissues, cells, organells, and molecules
How can the environment be organizes into levels from simple to complex?
The levels of an environment to be organized are populations,species,community,and the ecosystem
What are the biological sublevels of biotic community?
The biological sublevels of a biotic community include individual organisms, populations of the same species, and communities of different species interacting in the same habitat. These sublevels represent different levels of organization within the community, from individual organisms to larger groupings of species.
What are 6 different levels of organization that ecologists study?
Individual-->Population-->community-->ecosystem-->biome-->biosphere

How do you Compare population density maps?
To compare population density maps, you can visually examine the intensity of colors or shading in different areas of the maps. Darker or more densely colored regions indicate higher population density, while lighter or sparser regions suggest lower population density. You can also analyze numerical data associated with the maps, such as population figures or population per square kilometer, to quantify and compare the population density levels of different areas.
Is it true that a white tailed deer populations are at about the same levels as they were a century ago?
no
