Advantages of census of samples survey

1.	Advantages of census of samples survey
Answer» SAMPLE SURVEYSIn a sample survey, only part of the total population is approached for information on the topic under study. These data are then \'expanded\' or \'weighted\' to make inferences about the whole population. We define the sample as the set of observations taken from the population for the purpose of obtaining information about the population.Advantages of Sample Surveys compared with Censuses:\tReduces cost - both in monetary terms and staffing requirements.\tReduces time needed to collect and process the data and produce results as it requires a smaller scale of operation.\t(Because of the above reasons) enables more detailed questions to be asked.\tEnables characteristics to be tested which could not otherwise be assessed. An example is life span of light bulbs, strength of spring, etc. To test all light bulbs of a particular brand is not possible as the test needs to destroy the product so only a sample of bulbs can be tested.\tImportantly, surveys lead to less respondent burden, as fewer people are needed to provide the required data.\tResults can be made available quickly.
