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.
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 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.
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.
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.
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.
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.
What are the sources of hospital statistics?
Hospital censes,vital statistics, medical records, registers
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.
