Question

For a set population, does a parameter ever change? sometimes always unknown never if there are three different samples of the same size from a set population, is it possible to get three different values for the same statistic? data from samples may vary from sample to sample, and so corresponding sample statistics may vary from sample to sample. data from samples never vary from sample to sample, and so corresponding sample statistics never vary from sample to sample. data from samples never vary from sample to sample, and so corresponding sample statistics may vary from sample to sample. data from samples may vary from sample to sample, and so corresponding sample statistics never vary from sample to sample.

Answer 1

For a set population, does a parameter ever change?

Answer: For a set population, a parameter never change.

Because while computing the parameter each and every unit of the population is studied. Therefore, we can not expect a parameter to vary.

If there are three different samples of the same size from a set population, is it possible to get three different values for the same statistic?

Answer: Data from samples may vary from sample to sample, and so corresponding sample statistic may vary from sample to sample.

Because while calculating the sample statistic, we consider only the part of population. Every time we draw a sample from population, there is every possibility of getting different sample. Therefore, data from samples may vary from sample to sample and corresponding sample statistic may vary from sample to sample.
