Question

If there are three different samples of the same size from a particular population, is it possible to get three different values for the same statistic (e.g. the average age for each sample is different even though they come from the same population originally)?

a. Data from samples never vary from sample to sample, and so corresponding sample statistics never vary from sample to sample.

b. Data from samples may vary from sample to sample, and so corresponding sample statistics never vary from sample to sample.

c. Data from samples may vary from sample to sample, and so corresponding sample statistics may vary from sample to sample.

d. Data from samples never vary from sample to sample, and so corresponding sample statistics may vary from sample to sample.

Explanation / Answer

Data from samples may vary from sample to sample, and so corresponding sample statistics may vary from sample to sample.
