Its the group of the people that the selected group that completes the survey represents. For example if a teacher randomly selected ten kids for a survey to see what a classes favorite movie is. The class would be the population of that survey.

Is it better to survey as many people as possible.explain?
It is not always better to survey as many people as possible. The sample size needs to be representative of the population being studied to draw accurate conclusions. Too large a sample can be costly and time-consuming, while too small a sample may not provide reliable results. It is important to strike a balance between sample size and representativeness for meaningful survey results.
What percentage of surveys is required for validation and why?
There is no set percentage for the required sample size in surveys for validation. The necessary sample size depends on factors such as population size, margin of error, and confidence level. Generally, a larger sample size is needed for more accurate results, but it ultimately depends on the specific goals of the survey and the nature of the data being collected.

What is least likely to affect the validity of a public opinion poll or survey?
The size of the survey sample is least likely to affect the validity of a public opinion poll or survey, as long as it is conducted randomly. Other factors, such as biased questioning, nonresponse rate, or sampling method, are more likely to impact validity.
What are the differences between census and sample survey?
A census aims to collect data from every member of a population, while a sample survey collects data from a subset (sample) of the population. A census provides accurate and precise information for the entire population, while a sample survey estimates characteristics of the population based on the sample. A census can be time-consuming and costly, while a sample survey is more practical for large populations and can still provide valuable insights with less resources.
