Sampling Error: Sampling error refers to the difference between the sample statistic (e.g., sample mean or proportion) and the true population parameter due to random chance.
Representative Sample: A representative sample is a subset of a larger population that accurately reflects the characteristics of the entire population. It should be diverse enough to capture the variation within the population.
Margin of Error: The margin of error is a measure of how much uncertainty there is around an estimate based on a sample. It quantifies how reliable or accurate our estimate is likely to be compared to the true value in the population.
