Question

Quizplus · Accepted Answer

Sampling is used when it is not possible to collect information from the entire population, either due to its size, logistics, or cost. By collecting a representative sample of the population, researchers can make inferences about the larger group. Choosing a sample that is too small or unrepresentative can lead to biased or inaccurate conclusions. Additionally, sampling is not just useful in experimental designs, but also in non-experimental designs such as surveys or observational studies. It is important to avoid guessing and use statistical methods to ensure that the sample accurately reflects the population.
