Which statement, made by a research student, would the faculty analyze as indicating the student understands the concept of sampling distribution of the mean?
1. Sampling distribution is based on a finite number of samples from a population.
2. Theoretical sampling distribution of the mean eliminates error when calculating standard deviation in the sample.
3. Sampling distribution is used only in descriptive statistical testing.
4. The smaller the standard error of the mean, the more confidence the researcher can have that the mean from the sample is an accurate reflection of the population mean.
