sample
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.
Information obtained from the sample can be extrapolated to the whole population using statistics.
Sample is subset of the population so sample size and population size is different.However, as a subset can be the whole set, if the sample size equals the population size, you have sampled the entire population and you will be 100% accurate with your results; it may cost much more than surveying a [representative] sample, but you get the satisfaction of knowing for what you surveyed the population exactly.Using a sample is a trade off between the cost of surveying the whole population and accuracy of the result.A census is a survey of the whole population and could be considered that the sample size = population size; in this case the results are 100% accurate.The television viewing figures are calculated using a sample of the whole population and then extrapolating them to the whole population; depending upon how the same was chosen, including its size, will affect the accuracy of the results - most likely not more than 95% accurate.With a carefully selected (that is properly biased) sample you can prove almost anything!
It is not a sample. A sample must be a proper subset of the whole population.
In statistics, sampling is a process of collecting information from a subset of a population so as to reach conclusions about the whole population. This method is used because collecting information from the whole population is likely to be expensive and time consuming, and in some cases pointless. For example, if you tested the life expectancy of all light bulbs, you would have none left to sell!

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.
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.
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.
Click on the particular slice you want to explode, ensuring that it is selected. Then just drag it out. 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.
