What is population distribution?
Population distribution refers to the way in which people are spread across a geographical area. It can be characterized by factors such as population density, settlement patterns, and urban-rural divides. Understanding population distribution is important for government planning, resource allocation, and social services provision.

What type of sampling uses a fair representation of the population?
Stratified sampling is a type of sampling that uses a fair representation of the population by dividing the population into different subgroups or strata and then selecting samples from each stratum in proportion to their size in the population. This method helps ensure that all groups in the population are adequately represented in the final sample.
How do pollsters go about choosing people to answer their surveys?
The first stage, in any survey, is to establish some kind of register - the "sampling frame" - for the whole population that you wish to study. The accuracy of this frame can greatly influence the reliability of the survey results.The simplest method then is the simple random survey in which each member in the population is allocated a unique identifier. A suitable sample size is selected. Then a random number generating procedure is used to select identifiers until the required number are selected. This is the list of people who will be surveyed.Although statistically this list is representative of the whole population, you may be unlucky and get too many people of one kind or another. Also, the variability in the responses may differ between different subsets of the population. To overcome this, pollsters use stratified random sampling.In this scheme the total population is cross-classified into subsets, or strata, according to a number of criteria. For each criterion, people in the same subgroup should comprise of broadly similar people while people in different subgroups should be different. The stratifying criteria may be gender, age group, race, religion, educational attainment, income band or social group, political affiliations - in general any factor that is thought likely to affect the members' responses to the variable(s) of interest. Information on some of these factors may be available from the sampling frame. The rest would have to be established using preliminary profiling questions.A simple stratified scheme would be to treat each cross-classified subgroup as a population and take a simple random sample representing the same proportion in each subgroup. A more sophisticated process would be to estimate the variability (standard error) of the response variable(s) in each substratum. Then the sample size within each substratum is selected so as to bring the standard errors as close to one another as possible. Again, a simple random sample is chosen from each sub-population.Each stage in the process:establish the sampling frameidentify stratifying criteriaestimate variability of response in substratais a highly skilled process which could requiring substantial resources, including access to large sets of data and the results of related surveys.
How do you determine who you should survey?
The answer will depend on the sampling procedure. The choice of the smapling scheme (random, stratified, convenience etc) will each give different answers.The answer will depend on the sampling procedure.

What is population spacing?
Population spacing is the distribution of individuals in a certain area . Its classification is : CLUMP UNIFORM RANDOM
When is randomly distribution throughout an environment a population of deer that eats grass is most likely to have a pattern?
Random Pattern.
What is the difference between a population distribution and sampling distribution?
Population distribution refers to the patterns that a population creates as they spread within an area. A sampling distribution is a representative, random sample of that population.
What is random distribution in biology?
A random distribution is a random sample set displayed in the form of a bell curve. See random sample set.

What are patterns of population distribution?
Uniform - known as uniform or even distribution, this distribution pattern is characterized by the maximization of distance between any two individuals. Typically this is found in plants; they compete for a resource such as soil nutrients or moisture, so they space themselves far apart in order to maximize the amount of resource consumption. It can also be a result of territorial behavior as in penguin colonies.Clumped - the most common distribution pattern in nature, clumped distribution is the opposite of uniform: individuals minimize the space between others; as a result, "clumps" of species form around each other. This can be a result of unreliable resources. If one area tends to accumulate one resource important to the population, the individuals of the population will clump around this resource. It is also found among many animals to either aid predation or fend off predators. Hyenas, lions, and cheetahs hunt in packs to ensure a kill while schools of fish aggregate to minimize the chance that any one fish will be eaten.Random - in very homogenous environments, random or unpredictable spacing will occur, but this is not common in nature. For random distribution to occur, an individual of the population won't have any affinity or repulsion from another individual, nor will they have a preference for location due to biotic factors. Some examples of random dispersion include the random destinations of dandelion seeds dispersed by the wind and oyster larvae that are carried by water currents.

What is meant by bimodal distribution?
You are likely familiar with the probability density function of the normal distribution--that is, the bell-shaped curve.A bimodal distribution is one whose probability density function has two 'humps' or maxima. In other words, values of the random variable are more likely to occur around where those two maxima occur than elsewhere, in the same way that values of a normally distributed random variable are more likely to occur around its maximum.
