Random Sampling

Random sampling is a method used to select a group from a larger population in such a way that every individual has an equal chance of being chosen. This technique ensures that the sample represents the diversity of the population, which helps in making accurate conclusions about the whole group. For example, if you're surveying opinions about a new product, randomly selecting participants from different ages, genders, and backgrounds helps avoid bias and ensures a fair representation of the population's views. It’s a fundamental practice in research to achieve reliable and valid results.
