When is sampling more appropriate than taking a census

Yes, statistical sampling offers a more accurate method—at much lower cost—for determining population than does physical enumeration. No, the Supreme Court ruled that statistical sampling to calculate the population for apportionment violates the Census Act of Statistics—the mathematical science of analyzing numerical information—is vital to the practice of all the empirical sciences.

No modern science tries to account for the complexity of nature without using statistical methods, which typically provide investigators with a numerical outcome along with an analysis of the margin of accuracy of that outcome.

Why is a sample preferred to a census

With the help of computers, statistical techniques for collecting and analyzing large, complicated data sets have become very sophisticated and have proved to be reliable and effective for scientific researchers, inventors, and engineers working on problems in such diverse fields as economics, physics, and pharmaceuticals.

The popular perception of statistics, however, starkly contrasts with its valued role in the sciences. Statistics has often been dismissed as an unreliable and sinister "lies, damned lies, and statistics" strategy for manipulating data to support a pre-determined point of view.

While statistical techniques are quietly and successfully being used in many areas of modern life, one that most people are familiar and perhaps uncomfortable with is polling.

Because polls—which survey selected sample groups of people and then extrapolate the responses to a larger population—are often done on behalf of political causes or candidates, their interpretation can be controversial.

Bitter arguments about the outcome of a poll can taint the understanding of the statistical methods that made the poll possible. The census has become a particularly contentious area of debate over the use of statistics.

The census project seems deceptively simple: The census aims to count the population of the United States. But the population is large, diverse, moving, partially hidden, and changing every moment.

A physical "count" of the population could never be done, and even if it could it would only be accurate for a few seconds. Any effort to count the population will contain errors of identification and omission.

Under the time pressure measurement errors are more frequently made in the census rather than in a small sample. This interactive lecture activity motivates the need for sampling. "Why sample, why not just take a census?" Under time pressure, students count the number of times the letter F appears in a paragraph. Apr 16,  · Best Answer: Actually, a census typically uses sampling. However, I think I understand what you are asking.

Under the time pressure measurement errors are more frequently made in the census rather than in a small sample. Learning Goals The activity motivates the need for sampling.

The challenge that faces those who design and administer the census, then, is to proceed in a manner that will minimize those errors.

But the census poses much more than a scientific problem. The census is a political, economic, and social project, and those who are most interested in its outcome often have little regard for technical issues surrounding errors and estimates. As the population of the United States has grown and become more diverse, the census has become more difficult to administer.

It is well known that the standard method for performing the census, which relies primarily upon citizens to report information about themselves and their households and secondarily upon visits by census-takers to the homes of those who fail to report, undercounts the population by a significant amount.

The most obvious way to correct this problem seems to be to make use of statistical sampling methods, which could account for the variety within the population as the count is adjusted upward.

When is sampling more appropriate than taking a census

The undercount seems to be distributed unevenly throughout the population, tending to come primarily from certain groups that are harder to contact and locate, such as renters, immigrants, the homeless, and children.

These groups disproportionately tend to support Democrats rather than Republicans, thus leading to the primary political schism over the possibility of using statistical techniques to refine the census.

In What Types Of Situations Is Conducting A Census More Appropriate Than Sampling Census Method All items in any field of inquiry constitute a ‘ Universe ’ or ‘ Population.’ A complete enumeration of all items in the population is known as a census inquiry. Census vs. Sampling. Surveys can gather information through different methods of observation. However, most surveys employ a questionnaire to measure specific characteristics of the population. There are two main ways to gather this information. In what types of situations is conducting a census more appropriate than sampling? When is sampling more appropriate than taking a census? Best answer. % (1 rating).

Politicians view the undercounted groups either as potential supporters or potential opponents, and argue accordingly about how to count them.

Opponents of the use of statistical sampling to improve the census attack on several fronts and take advantage of public skepticism about the validity of statistical methods. They argue that the Constitution quite literally calls for a physical enumeration a physical counting of the population to be performed during each decade's census, and use this as a foundation to block any effort to incorporate statistical modifications.

Various legal issues surrounding Constitutional interpretation have been argued all the way to the United States Supreme Court. Incorporated in these legal challenges are criticisms of the statistical methods that would be used to improve the accuracy of the census. While members of the National Academy of Sciences as well as other mathematical and scientific experts have generally endorsed the superior accuracy of statistical sampling over enumeration, laymen remain somewhat perplexed and skeptical.

One reason for that concern may be a form of circularity in the argument of sampling's proponents; that is, in order to argue that sampling gives a more accurate count, they use evidence collected by sampling. What sampling's advocates call accuracy, its critics call bias.

Courts are notoriously poor places to settle technical disputes, and the debate over census methods is no exception. Because the census affects the creation of political districts and the apportionment of financial resources, however, it is inevitable that any change in its methods will be assessed on political as well as scientific grounds.Under the time pressure measurement errors are more frequently made in the census rather than in a small sample.

This interactive lecture activity motivates the need for sampling. "Why sample, why not just take a census?" Under time pressure, students count the number of times the letter F appears in a paragraph.

Sampling for nonresponse follow-up was predicted to reduce the Census Bureau's total workload, which would permit improvements in the control and management of field operations, and which would allow more complete follow-up of difficult cases, leading to an increase in .
