What are examples of: 1. Sampling Error. 2. Sampling Distribution of Sample Means 3. Central Limit Theorem. 4. Standard Error of the Mean. The standard error of the estimate of the mean is represented by the equation: σ√n Discuss what this equation means, using your own words and explain why we use it. Consider how it relates to the fact that we are making assumptions about the population and not just the sample.
