Suppose that the average grade point average (GPA) for the undergraduate student population at Goldey-Beacon College is 3.10. The following is a random sample of the GPAs of five students from the college. Calculate and interpret the sampling error.

2.45 3.76 3.48 2.81 3.34

Solution

Sampling error =sample mean -population mean=3.17-3.10=0.07.
