What is the primary purpose of sampling?

The primary purpose of sampling is to select a subset of items from a population of interest. By choosing a representative portion of the population, researchers can make inferences and draw conclusions about the larger group without the necessity of surveying every individual. This approach saves time, reduces costs, and minimizes the logistical challenges that come with studying an entire population.

Sampling is particularly beneficial in various research scenarios where it would be impractical or impossible to collect data from every member of a population, such as in large-scale studies or when the population is constantly changing. The insights gained from the sample can then be extrapolated to understand trends, behaviors, or characteristics within the whole population.

In contrast, while surveying every individual from the population may seem thorough, it is not practical or efficient in many cases. Likewise, gathering qualitative data is a specific aspect of research but does not encompass the broader purpose of sampling. Creating a complete database of the population is also unnecessary in the context of sampling since the goal is to obtain knowledge about the population through a smaller group rather than documenting every detail about it.
