Random sampling is a statistical technique used to select a subset of individuals from a larger population. The key feature of random sampling is that every member of the population has an equal chance of being chosen. This method helps ensure that the sample is representative of the entire population, reducing bias in the results.
By using random sampling, researchers can make more accurate inferences about the population based on the sample data. This technique is commonly used in various fields, including surveys, polling, and scientific research, to gather information and draw conclusions that are valid and reliable.
