A sample is a portion and a census measures absolutely everyone in the whole country. A representative sample measures a small number of people who fit a particular category of people: surveying 200 white male smokers between 20 and 40 who have had surgery for throat cancer (out of a total number of say 35,000 men who fit that profile).

A census aims to collect data from every member of a population, while a sample survey collects data from a subset (sample) of the population. A census provides accurate and precise information for the entire population, while a sample survey estimates characteristics of the population based on the sample. A census can be time-consuming and costly, while a sample survey is more practical for large populations and can still provide valuable insights with less resources.

Briefly explain the differences between a census and a sample survey?
A census collects data from every member of a population, while a sample survey collects data from a subset (sample) of the population. A census provides a complete count and is more accurate, but requires more resources and time. A sample survey is faster and more cost-effective, but has a margin of error as it extrapolates findings from a smaller group to represent the larger population.
Difference between a Census and a Survey?
A census aims to collect data from an entire population, while a survey gathers information from a sample of the population. Censuses are comprehensive and usually mandatory, whereas surveys are typically voluntary and sample-based. Censuses are used to provide official population counts and demographic data, while surveys are often conducted to gather specific information on a particular topic.
What are the similarities btn census and sample survey?
Both census and sample survey are methods used to collect data from a population. However, while a census attempts to gather information from every individual in the population, a sample survey collects data from a subset of the population. Both methods aim to provide insights and statistics about the population under study.
Which one is more accurance census or sample survey?
A census is more accurate than a sample survey because it aims to collect data from an entire population, leaving no room for sampling error. However, conducting a census can be costly and time-consuming, while a sample survey is more practical for large populations.
Survey sampling is better than census survey?
Survey sampling involves selecting a representative subset of the population, which can be more practical and cost-effective than surveying the entire population in a census. Proper sampling techniques can still provide accurate and reliable results, as long as the sample is chosen correctly and is representative of the population of interest.
What is the difference between census and sample survey?
A sample survey is asked of a limited group of people, while a census is conducted in an attempted to get an answer from all people in a geographical area.
What is the difference between a sample and a census?
A Census is the type of survey for a complete population. A Sample Survey is only a portion of the population which is used to make predictions on the representation of the actual population.

What is census in statistics?

Why is sample survey better than a census?
becuase it is more accurate.
Why is conducting a sample survey preferable to conducting a census?
A sample survey may be preferable than a census because it can be more comprehensive. While its research only involves a subset, it is typically more accurate.
What is the difference between population survey and sample survey?
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.
What is the advantage of samle survey over census?
A sample survey is quicker and cheaper. If the survey is well designed then the results are likely to be close to their true values.
Merits and demerits of sample survey?
Merits: Sample surveys are cost-effective, time-efficient, and allow for data collection from a large population subset. They can provide valuable insights into attitudes, opinions, and behaviors. Demerits: Sample surveys may suffer from sampling bias, leading to results that are not representative of the population. There can also be issues with survey design, response rates, and interpretation of results.
