Sampling error refers to the natural variation that occurs when researchers take a sample from a larger population. This variation can occur due to chance alone and cannot be completely avoided. Sampling bias refers to the systematic errors that occur when certain traits or characteristics of the population are over-represented or under-represented in the sample. Random error refers to the variability that occurs due to chance factors that are unpredictable and can occur in any direction. Design flaws refer to issues with the research design, such as poor measurement tools or inadequate sampling methods. Therefore, the best answer is C because it specifically refers to the natural tendency of samples to differ from populations and from each other.
