Thread: Probability Sampling Question

True or False? Nonprobability sampling is particularly useful in quantitative studies.


True or False? If two samples of the same size are drawn from the same population using simple random sampling, it follows that they will have the same statistics.

Anyone? Give why you think each is true or false. Thanks

This is false, recall the idea of a confidence interval for signifcance . If you take 100 different samples of size n where n is large enough and then construct the interval for each sample then % of these intervals will contain the population mean.
