Law of Large NumbersLarge samples will be representative of the population from which they are scoredSampling ErrorNatural discrepancy, or amount of error, existing between a sample statistic and its corresponding population parameterSampling Error- a consequence of the fact that samples vary in their estimates of the population mean
