The population is every data point you intend to generalise the survey results to. The sample frame is those data points that you can pick from for the survey. The sample is which of these data points you actually survey, and the sample size is how many of those data points there are.
For instance, if you have 700 students in a school, and you have access to 300 of them, and decide to give 30 of them a survey, the sample size is 30.
There is no "ideal" sample size for any given population, because polls and other statistical analysis forms depend on many factors, including what the survey is intended to show, who the target audience is, how much statistical error is permitted, and so on. The "Survey System" link, below, offers definitions and a couple of calculators to determine the best sample size for most purposes.
According to the website Survey System's Creative Research Systems page, you can use a sample size calculator to determine how many people need to be interviewed in order to meet your target.

A population survey, better known as a census, entails the collection of each unit in the population. In sample survey information is collected from a subset of the population. The subset, or sample, needs to be selected carefully so that it is representative of the whole population and, if that requirement is met, statistics based on the sample are good estimators for the corresponding population parameters.
a larger the sample size will reduce the size of the confidence interval
It is because the sample size for the second survey was larger.
The leading questions in a sample survey is the purpose of the survey and the expectations of the interviewees.
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. sources- 7th grade advanced math class, we just did surveys :) :) -J
