Random selection is a method used to choose individuals or items from a larger group in a way that ensures each member has an equal chance of being selected. This technique is commonly used in research, surveys, and experiments to avoid bias and ensure that the sample accurately represents the population. In practice, random selection can be achieved through various means, such as using a random number generator or drawing names from a hat. This approach is essential in fields like statistics and social science, where the validity of results depends on the randomness of the sample chosen.
