Statistical question
You are studying the sample because you want to find out information about the whole population. If the sample you have drawn from the population does not represent the population, you will find out about the sample but will not find out about the population.

If the whole pie is selected, all slices will explode, which is why it is important to make sure only one slice is selected before dragging.Click on the particular slice you want to explode, ensuring that it is selected.

A sample is a smaller group selected from a larger population. It may be to costly and time consuming to carry out the study on the whole population so the researchers choose a sample and often generalise results.A sample frame is the list of people from which a sample for the study are selected. It is only carried out on the target population that the researcher is interested in studying. For example finding data on just school children would not involve the the whole population only children in schools.
Because a sample is information obtained from the population that will be used in hypothesis testing. WER 1.19.2011 Samples are used to save time and money when the population is large and when the units must be destroyed to gain information.
Cluster sampling is a scheme which is used when sampling from the whole population would be too expensive - in terms of time or money. The sample space is divided into clusters, a random sample of clusters is selected and then every member of the population within the selected clusters is studied.For example, suppose you wanted to collect information from schools across a country and had calculated that a 5% sample was required. Rather than criss-crossing the country, you could divide the country into units: for example counties. You then select counties (your clusters) so that they cover 5% of the nation's schools. Visit each chosen county and sample all schools in it. The selection of counties would probably also need to be controlled so that urban and rural areas are properly represented.
sample
A sample group
A population survey, better known as a census, entails the collection of each unit in the population. In sample survey information is collected from a subset of the population. The subset, or sample, needs to be selected carefully so that it is representative of the whole population and, if that requirement is met, statistics based on the sample are good estimators for the corresponding population parameters.
False
Information obtained from the sample can be extrapolated to the whole population using statistics.
Both being sub-parts of probability sampling, Random sampling differs in the sense as the sample is chosen out of a whole population randomly. whereas cluster sampling is extracted from a population already been selected by the same organization. eg. out of a whole population an area is selected by the management, which is the cluster, and is handed over to you to perform the tests necessary. Stratified sampling on the other hand is extracted according to the the categories the selected sample belongs to. These sectors selected might be on the basis of their nature of work, dealings etc. eg. industrial, commercial, residential and so on.
Sample. A random sample ensures that everyone or thing has a proportionally equal chance of being picked. The idea is that the sample should be representative of the whole population.

First of all, the prey of the blue crab would decrease in population and the predators would increase in population. As a result the whole food chain would be thrown off.
