In random sampling, each member of the population has an equal chance of being chosen, which minimizes selection bias and improves the likelihood that the sample accurately reflects the population. Non-random sampling, on the other hand, often involves selecting individuals based on specific criteria, making it subjective and more prone to bias. This can affect the sample’s representativeness, although non-random sampling is sometimes used in cases where convenience or specific characteristics are necessary. Option A is incorrect because sample size is determined by study requirements, not the sampling method. Option B is incorrect as non-random sampling is applicable to both small and large datasets. Option D is incorrect because random sampling is typically more reliable in reducing selection bias. Option E is incorrect as random sampling is specifically designed to produce representative samples.
