Advantages of census over sample survey?

It is more accurate, unbiased and includes every item in the population, whereas sampling may be biased, and sampling is not totally representative.


Advantages of census over Sampling in Statistics?

There are several advantages of sampling over census (i.e. selection of wholepopulation for analysis).Firstly, the costs on sampling should be much lower than that on census. For example,for the government by-census (note: population census is usually conducted onceevery ten years and a by-census is conducted in the middle of the intercensal period),one fifth of the population is large enough to declare what the government wants toknow. There is no need to spend several times of dollars to interview the entirepopulation in the society.Secondly, a quality guru (Deming, 1960) argued that the quality of a study was oftenbetter with sampling than with a census. He suggested that, "Sampling possesses thepossibility of better interviewing(testing), more thorough investigation of missing,wrong , or suspicious information, better supervision, and better processing than ispossible with complete coverage". Research findings substantiate this opinion. Morethan 90% of survey error in one study was from non-sampling error1, and 10% or lesswas from sampling error2. (Donald et al., 1995)Thirdly, sampling can save the time. The speed of execution reduces the time betweenthe recognition of a need for information and the availability of that information.1 Non-sampling error is the error of research due to factors other than the sample size and samplingmethod, including non-response, bad communication with interviewees, measurement error, etc.2 Sampling error is the error during research due to the sample size and sampling method.

Are there advantages and disadvantages to conducting a census?

The advantages of conducting a census are that the figures that are received are vital for planning and development purposes. The authorities can make plans for infrastructure according to the population trends. Some disadvantages arise regarding the validity of the figures collected. Wrong figures ultimately mean that the wrong factors are being considered.

Why do we need sampling in which sistuations sampling over census?

A census requires you to obtain information for every member of the population. This may be very expensive, time-consuming. Also, not all members of the population may provide a response.If the information that is sought is destructive, then a census defeats the purpose. For example, if you wanted to test the breaking point of a safety harness and carried out a census, you would have precise information on the breaking point but no harnesses left!If the information that is sought is not very variable, then a well designed sample is quicker, cheaper and can be made sufficiently accurate.
