Key Terms Equations Important Chapter 7 Notes Sampling Error- The error resulting from using a sample to estimate a population characteristic. = ẋ - µ For a given variable x and a given sample size, the distribution of the variable ẋ is called the sampling distribution of sample size. Sampling error is the distance between the sampling mean and the population mean. ẋ gets closer to the mean as we increase n (size) Mean of sample means= population mean µẋ=µ Standard deviation of sample mean ᶞ = ᶞ ẋ n If variable population is normal than sample size (n) is also normally distributed Central Limit Theorem: For relatively large sample sizes
