Survey sampling is better than census survey?
Only in terms of cost, time to complete, resources-those kinds of measures. A census provides complete information if done properly which is not possible with just a sample. A sample is always subject to sampling error.
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 scientifically valid sample?
Scientifically valid samples are those that accurately represent the population being studied, ensuring that findings can be generalized. They should be selected using appropriate sampling methods, such as random sampling, to minimize bias. Additionally, sample size must be sufficient to provide reliable and statistically significant results. Valid samples also adhere to ethical standards and maintain the integrity of the research process.
What are the characteristics of good sample?
A good sample is representative of the larger population it is drawn from, ensuring that its characteristics mirror those of the whole group. It should be sufficiently large to provide reliable results and minimize sampling error. Additionally, a good sample is selected using appropriate methods to avoid biases, allowing for generalizable conclusions. Random sampling techniques often enhance the validity of the sample.
What are the steps you must take to get an accurate poll?
To conduct an accurate poll, first, define a clear, unbiased question to ensure that it captures the intended information. Next, select a representative sample of the population using random sampling techniques to avoid bias. Ensure the sample size is sufficient to provide statistically significant results. Finally, analyze the data carefully, taking into account potential sources of error and bias, and report the findings transparently.
The most reliable measure of public opinion is?
Surveys and polls conducted using random sampling are generally considered the most reliable measure of public opinion. By ensuring a representative sample of the population is included, these methods provide insights into the attitudes and preferences of a broader audience.
What are the advantages and disadvantages of acceptance sampling?
1).There may errors (Producer's and Consumer's risk) associated with the sampling. 2).The sample does not provide 100% accurate information of the condition of the bacth.
Why business might use quota sampling in market research?
Businesses may use quota sampling in market research to ensure that the sample represents important subgroups within the target population. This method allows for easier identification and recruitment of participants from specific demographic groups, making it more cost-effective and efficient. Quota sampling can help provide more accurate and reliable data for making informed marketing decisions.

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 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.
