A random sample is important because it ensures that each individual in the population has an equal chance of being selected, therefore reducing sampling bias. A controlled sample or a verifiable sample are not necessarily relevant for making decisions about a population. While a large sample is useful, it is not the only factor to consider, and a small random sample may still give a representative picture of the population.
