There are several reasons why a researcher may choose to use sampling instead of surveying the entire population. Some of these reasons include:
1. Cost-effectiveness: Surveying an entire population can be time-consuming and expensive. By using sampling, researchers can gather data from a smaller subset of the population, which can save time and resources.
2. Feasibility: In some cases, it may be logistically impossible to survey an entire population. For example, if the population is very large or spread out geographically, it may be more practical to use sampling.
3. Accuracy: Sampling can provide a representative snapshot of the population, without the need to survey every single individual. By using appropriate sampling techniques, researchers can ensure that their sample accurately reflects the characteristics of the population.
4. Ethical considerations: In some cases, surveying an entire population may not be ethical or practical. For example, if the research involves sensitive topics or vulnerable populations, it may be more appropriate to use sampling to protect the privacy and well-being of participants.
Overall, using sampling in a survey allows researchers to gather valuable data in a more efficient and practical manner, while still ensuring that their results are reliable and valid.

There are several reasons why a researcher might use sampling instead of population in a survey:
Cost and Time: Surveying an entire population can be prohibitively expensive and time-consuming. Sampling allows researchers to obtain data from a smaller, representative subset of the population, which is more cost-effective and efficient.
Practicality and Accessibility: In many cases, it is simply not feasible to survey every single member of a population. This could be due to geographical constraints, time limitations, or other factors that make it difficult to reach all individuals.
Representativeness: Sampling methods are designed to ensure that the sample is representative of the target population. This means that the characteristics of the sample should reflect the characteristics of the entire population, allowing researchers to generalize their findings to the larger group.
Precision: By selecting a sample that is large enough and representative, researchers can achieve a desired level of precision in their results. This means that the sample estimates are likely to be close to the true population values.
Flexibility: Sampling allows researchers to tailor their surveys to specific objectives and constraints. They can select different sampling methods and sample sizes depending on the research question, available resources, and time frame.
Confidentiality and Privacy: In certain situations, it may be necessary to protect the confidentiality and privacy of respondents. Sampling allows researchers to collect data from individuals without revealing their identities or sensitive information.
Overall, sampling is a practical and cost-effective method that enables researchers to obtain reliable and generalizable data from a representative subset of the population.
