What else can I help you with?
A sample that does not reflect the population would result from?
Under-Coverage
A convenience sample will usually result in?
under coverage
Why might researchers study just a sample of a large population rather than the whole population?
Because the whole population might be too large to sample. A good example is the population of the world. At nearly 7 billion people, it would be unrealistic to sample each person to determine some factor that you are looking at. Generally, we sample a subset of the population, taking into account differences (or errors) that might result, in this case, regional and cultural, in order to estimate the behavior of the larger population.
If a population consisted of 75000 people surveying 75000 people from the population could result in a parameter but not a point estimate.?
Well, isn't that just a happy little mistake! When you survey the entire population, you're looking at the actual parameter, not an estimate. A point estimate comes from sampling just a portion of the population, giving you an idea of what the parameter might be. Just remember, there are no mistakes in statistics, only happy little accidents!
Factors that determine sample size?
1. population to deal with in the sample 2. Location. ocation where the sample will be done 3. design. how the sample will be taken 4. result. how the outcome will be determined
How do you find the pupulation density of an area?
-- Find out the population of the area. -- Find out the area of the area. -- Divide the population by the area. The result is the population density of the area.
Will higher density rise?
Higher density can result in vertical growth or increased development within a given area, but it depends on various factors such as zoning regulations, infrastructure capacity, and market demand. Communities often consider density management strategies to balance population growth with livability and environmental considerations.
What is calculated by dividing the population by its land area?
Population density is calculated by dividing the population of a region by its land area. This measurement helps to determine how crowded or sparsely populated an area is.
Population growth is limited by density-dependent factors such as what?
Population growth is limited by density-dependent factors such as competition for resources, predation, disease, and parasitism. As a population increases in size, these factors become more pronounced, leading to increased competition for food and space, higher transmission rates of diseases, and greater vulnerability to predators. This can result in reduced reproductive rates and higher mortality, ultimately stabilizing or decreasing the population size.
Sentence for decline?
There was a decline in the population as a result of the war.
Will a high density have a lower or higher number?
A high density will have a higher number, as density is calculated by dividing mass by volume. The result is a measure of how much mass is present in a given volume, so a higher density means there is more mass packed into that volume.
How do parasites serve as a density-dependent limiting factors?
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
What is dispersed population density?
Dispersed population density refers to a population that is spread out over a large geographic area. This can result in a lower overall population density because people are not concentrated in specific areas. It can present challenges for providing services and infrastructure to widely dispersed communities.
What is a population control factor whose effects increase the size of population?
Increased immigration can lead to a larger population by adding more individuals to the existing population. This can result in higher birth rates due to increased availability of potential partners and greater genetic diversity.
Why can we float easier in the sea than in a freshwater lake?
The density of salt water is higher than fresh water.
How do you show evidence of the higher the mass the higher the density and the hgher the volume the lower the density?
The only "evidence" you need is the definition of density, which is mass divide by volume. For example, if you divide the same mass by a larger volume, you get a smaller result.
How does population density affect the way people live?
High population density can lead to crowded living conditions, increased competition for resources, and higher levels of pollution. It can also result in the development of vertical living spaces such as high-rise buildings and apartment complexes. Conversely, low population density may allow for more spacious living arrangements, better access to natural areas, and reduced traffic congestion.
