Survey sampling is better than census survey?

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 are the advantages and disadvantages of POISSON sampling method?
Advantages of Poisson sampling method include its simplicity and ease of application, as well as its ability to provide unbiased estimates of population parameters. Disadvantages may include potential underrepresentation of rare events or small subgroups in the population, as well as the assumption of random and independent sampling.

What are the different advantages of Sampling?
Sampling allows researchers to collect data from a smaller subset of a population, saving time and resources. It can provide insights into the characteristics of a larger population without having to survey everyone. Additionally, sampling can reduce bias in data collection and improve the overall quality of research findings.
What are the merits and demerits of sampling methods?
Advantages and Limitation of Sampling: 1. Sampling saves time and labour. 2. It results in reduction of cost in terms of money and manhour. 3. Sampling ends up with greater accuracy of results. 4. It has greater scope. 5. It has greater adaptability. 6. If the population is too large, or hypothetical or destroyable sampling is the only method to be used. The limitations of sampling are given below: 1. Sampling is to be done by qualified and experienced persons. Otherwise, the information will be unbelievable. 2. Sample method may give the extreme values sometimes instead of the mixed values. 3. There is the possibility of sampling errors.
What is the procedure of convenience sampling?
Convenience sampling is also know as grab sampling. There is no procedure for the sampling itself because the emphasis at this stage is usually on improving other aspects of the research such as exposing flaws in a survey form or training personnel. In grab sampling you simply take any sample element that you can find although you might favour those that would exercise parts of your system that might seem weak. For instance, if your survey instrument asks for ages and some people were reluctant to provide them, then how would this be resolved once the grab sampling phase had been completed and actual sampling had started?
