Less time and less cost for a sample.
Sample is preferred to population because observing the population can be impossible due to its size. You take a random sample of the population and, with statistics, you can infer things about that population to various degrees of confidence based on the sample size and on other knowledge about the population. For instance, if you wanted to know how many people on earth have brown hair, you would not check all 6 billion people - you would create a sample set, say a few hundred, thousand, or whatever - count the number with brown hair - and then run your calculations.
Sampling can be more accurate than a census as there is greater control of interviewers and less chances of mistakes being made as the data is collated

A composite sample is taken over a period of time, while a grab sample is a snap shot of what is in your well at the time you take the sample. Homeowner samples are generally grab samples.

In the pharmaceutical industry, a composite sample is a combination of multiple individual samples collected from different locations or batches to create a representative sample for analysis. This approach helps in assessing the overall quality and uniformity of a product, ensuring that variations within a batch are accounted for. Composite sampling is particularly useful in stability testing, quality control, and regulatory compliance, as it provides a more accurate reflection of the entire lot's characteristics. By analyzing a composite sample, manufacturers can identify potential issues and ensure that products meet strict safety and efficacy standards.
You can grab the video off your Xbox 360 if your capture card accepts component or composite signals.
Composite toe and steel toe safety shoes have the same function and meet the same standards, so they are interchangeable in most circumstances. Composite might be preferred to steel if you are working around electricity or in cold environments.

This cannot be answered Until and Unless a certain set of numbers are given as Sample Space.
1) when the fixed cost of selecting a sample is high. 2) when there is high variability in the characteristic been measured. 3) when the population is small.
