Document Summary

Why does sampling error occur: sampling error: naturally occurring discrepancy (error) that exists between a sample statistic and the corresponding population parameter, why: a sample typically will not provide a perfectly accurate representation of its population. There typically is some discrepancy (or error) between a statistic computed for a sample and the corresponding parameter for the population. In general, there will be some discrepancy, or sampling error, between the mean for a sample and the mean for the population from which the sample was obtained: imagine that you have conducted a study on two samples. When you compare the samples" scores, you find a difference. What are the two ways to interpret that difference: (cid:883). No real difference between the two and it"s a sampling error: 2. What type of relationship does it illustrate between variables: two different variables are observed to determine whether there is a relationship between them.
